OPINION
AFFIRMED BIRCH, J.
We granted the defendant’s application for permission to
appeal in order to determine whether the trial court abused its
discretion1 in admitting testimony concerning the results of a
certain method of DNA analysis. While we have previously considered
the admission of the results of DNA analysis using the “restriction
fragment length polymorphism” (RFLP) method, we address for the
first time the admission of testimony regarding DNA analysis using
the “polymerase chain reaction” (PCR) method. PCR is to be
distinguished from RFLP, the method more statistically precise and
firmly established in both the scientific and legal community.
After a jury-out hearing, the trial court admitted expert testimony
about the results of the PCR analysis performed on the defendant’s
clothing, and the Court of Criminal Appeals upheld the trial court’s
determination.
For the reasons stated, we conclude that the PCR method of
DNA analysis is a “DNA analysis” within the definition of Tenn. Code
Ann. § 24-7-117(a) (Supp. 1991)2 and is therefore exempt from a
1
Abuse of discretion is the standard for review of a trial
court’s admission of scientific evidence. State v. Ballard, 855
S.W.2d 557, 562 (Tenn. 1993).

Section 24-7-117 provides:
(a) As used in this section, unless the context
otherwise requires, “DNA analysis” means the process
through which deoxyribonucleic acid (DNA) in a human
biological specimen is analyzed and compared with DNA from
another biological specimen for identification purposes.
(b)(1) In any civil or criminal trial, hearing or
proceeding, the results of DNA analysis, as defined in
subsection (a), are admissible in evidence without
antecedent expert testimony that DNA analysis provides a
trustworthy and reliable method of identifying
characteristics in an individual's genetic material upon
a showing that the offered testimony meets the standards
2
judicial determination of reliability and trustworthiness, as would
normally be required under Tenn. R. Evid. 703.3 Furthermore, the
expert testimony adduced at trial satisfied the relevancy
requirements of Tenn. R. Evid. 4014 and was of substantial
assistance to the trier of fact as required by Tenn. R. Evid. 702.5
of admissibility set forth in the Tennessee Rules of
Evidence.
(2) Nothing in this section shall be construed as
prohibiting any party in a civil or criminal trial from
offering proof that DNA analysis does not provide a
trustworthy and reliable method of identifying
characteristics in an individual's genetic material, nor
shall it prohibit a party from cross-examining the other
party's expert as to the lack of trustworthiness and
reliability of such analysis.
(c) In any civil or criminal trial, hearing or
proceeding, statistical population frequency evidence,
based on genetic or blood test results, is admissible in
evidence to demonstrate the fraction of the population
that would have the same combination of genetic markers as
was found in a specific biological specimen. For purposes
of this subsection, “genetic marker” means the various
blood types or DNA types that an individual may possess.
3
Rule 703 states:
The facts or data in the particular case upon which
an expert bases an opinion or inference may be those
perceived by or made known to the expert at or before the
hearing. If of a type reasonably relied upon by experts
in the particular field in forming opinions or inferences
upon the subject, the facts or data need not be admissible
in evidence. The court shall disallow testimony in the
form of an opinion or inference if the underlying facts or
data indicate lack of trustworthiness.
4
Rule 401 states:
“Relevant evidence” means evidence having any
tendency to make the existence of any fact that is of
consequence to the determination of the action more
probable or less probable than it would be without the
evidence.
5
Rule 702 states:
3
Therefore, the results of the PCR analysis in this case were
properly admitted, and the defendant's convictions and sentences are
affirmed.
Because the defendant does not contest the sufficiency of
the convicting evidence,6 a brief summary of the facts is sufficient
to place the issue into context.
The record reveals that the defendant, Bobby Ed Begley,
lived in the house next to the house of Delma Johnson, age 72. They
were acquainted with each other; Begley had been to Johnson’s house
on several prior occasions to use Johnson’s telephone. On February
5, 1993, Begley went to Johnson’s house and asked to borrow $10;
Johnson handed the $10 to him. When Begley offered to return the
$10 later that evening, Johnson admonished him repeatedly that he
should not do so.
In spite of the admonishments, Begley returned later that
evening. As soon as Johnson opened the door, Begley rushed in past
If scientific, technical, or other specialized
knowledge will substantially assist the trier of fact to
understand the evidence or to determine a fact in issue,
a witness qualified as an expert by knowledge, skill,
experience, training, or education may testify in the form
of an opinion or otherwise.
6
After this application was granted the defendant asked the
Court to consider whether counts three through eight of the
indictment, under which he was convicted of aggravated rape, were
fatally deficient by their failure to allege the requisite mens rea
element of aggravated rape. Consistent with our decision in State
v. Hill, No. 01-S-01-9701-CC-00005 (Tenn. filed Nov. 3, 1997), we
find that the failure of the indictments in this case to allege a
specific mens rea does not affect the validity of the defendant’s
convictions. We decline to address this issue further.

her. He beat and battered her severely. He sexually penetrated her
several times. He then stuffed her into the trunk of her car,
closed the trunk, and drove off.
He drove a short distance and stopped. He pulled Johnson
out of the trunk and dumped her in some bushes. The temperature
was below freezing that night, and Johnson was wearing only a
nightgown and robe.
Approximately two to three hours passed before Johnson was
discovered and rescued. She was in poor condition and weak from
loss of blood. However, at the hospital she was able to identify
Begley as her assailant, and she identified him again at trial.
Arresting officers observed what appeared to be blood on
Begley’s trousers. The trousers were seized, and the blood spots
were subjected to DNA analysis at a biomedical laboratory in North
Carolina.
Following a jury trial, the defendant was convicted of
especially aggravated kidnaping, attempted first-degree murder,
aggravated robbery, and several counts of aggravated rape.
I
A brief and simplified explanation of the theory and
methods of DNA analysis will be helpful at the outset. The
5
Washington Supreme Court gave the following general explanation
about the nature of DNA:
DNA (deoxyribonucleic acid) is the
chemical material contained within an
organism's cells which determine[s]
that organism's physical composition.
Human cells each contain 46
chromosomes, which are arranged in 23
pairs. One chromosome in each pair
is inherited from each parent.
Approximately 100,000 genes are
located on the chromosomes. Genes,
which consist of DNA, determine eye,
hair, and skin color, the
organization of body parts, and
virtually everything else about our
physical state. Each individual,
with the exception of identical
twins, has a unique DNA structure
which is contained in every nucleated
cell. That structure remains constant
throughout a human lifetime. It can
be found in blood, semen, hair, bone
marrow, and other tissues.
State v. Cauthron, 846 P.2d 502, 508 (Wash. 1993) (footnote
omitted). The DNA analysis at issue in this case is more
specifically known as DNA typing. Ninety-nine percent of the DNA
molecule is the same for every individual.7 Polymorphisms are the
DNA segments which exhibit genetic variation within the population.
These variations provide the basis for DNA typing. DNA typing is
used to determine whether biological material from a known
individual can be linked to a sample from an unidentified specimen.
7
Only three million of the three billion-odd base pairs of the
DNA molecule differ from one individual to the next. National
Research Council, The Evaluation of Forensic DNA Evidence 63 (1996).
6
Forensic applications of DNA typing involve two
components: molecular biology and population genetics. Molecular
biological techniques, such as the RFLP and PCR methods, permit
scientists to extract and examine unidentified DNA from a given
piece of evidence. In the PCR method, the sample of DNA is
subjected to an enzyme and heating treatment, which causes a
specific segment of the DNA to be “amplified” by billions of
replications. To determine whether two samples could have come from
the same person, the samples are compared to see if they produced
the same pattern. Thomas M. Fleming, Annotation, Admissibility of
DNA Identification Evidence, 84 A.L.R.4th 313, 323 (1991). In the
RFLP method, an enzyme treatment cuts the DNA molecules into
fragments. The resulting length and location of these fragments
differ among individuals; samples are then compared to see if they
match. Id. at 320.
Population genetics is then used to determine the degree
to which two samples are similar by greater than a random chance.
The Alaska Court of Appeals explained:
Theoretically, each person's DNA
is unique; that is, with the
exception of “identical twins,” no
two persons share exactly the same
complement of genes. At the same
time, however, it is rare for a
specific gene to be unique to a
single individual. Some genes--for
instance, the genes that direct our
bodies to form two arms and two
legs--are found in virtually every
human being. Other genes, such as
those that determine skin, hair, and
eye color, are shared by substantial
numbers of people. Still other genes
are so rare that they are shared by
7
only small percentages of the general
population. . . .
That genes8 are shared by groups
of people is of crucial significance
when DNA testing is employed to
identify the perpetrator of a crime.
Even though DNA testing can
accurately identify a person's genes,
the fact that a person carries a
particular gene means little unless
scientists can also tell us the
likelihood that other people share
that same gene. The fact that a
defendant carries the same gene as
was found in a tissue sample taken at
the scene of the crime is not
particularly probative if a high
percentage of the population also
carry that same gene; conversely, if
the gene is quite rare, then the DNA
match becomes correspondingly more
probative.
Harmon v. State, 908 P.2d 434, 440-41 (Alaska Ct. App. 1995)
(footnote omitted).
Both the RFLP method and the PCR method have advantages
and disadvantages. The most significant advantage of the RFLP
method is its specificity. Through application of statistical
population frequency evidence to the test results, the RFLP method
narrows the possible contributors of a given sample to an
infinitesimally small portion of the population, and in doing so
informs the jury of the likelihood the sample was contributed by
someone other than the defendant. On the other hand, the RFLP
8
Although the Alaska Court of Appeals used the term “genes”
when explaining the DNA testing process, they recognized that it is
actually certain alternative forms of a particular gene, known as
“alleles,” which are copied and compared in this process.
Technically, it is the frequency with which these alleles occur in
a given population which is examined to exclude or not exclude a
certain suspect as the source of the unknown DNA. The court used
the term “genes” for the sake of simplicity.
8
method is time-consuming and requires a large quantity of high-
quality genetic material--at least a quarter-sized stain of blood or
a dime-sized stain of semen is required to perform the RFLP method
of DNA analysis. Also, unless the samples are recovered when
relatively fresh, they degrade into fragments too small for the RFLP
method.
In contrast, the PCR method can be performed with very
small amounts of genetic material, since the process itself allows
amplification to produce an amount suitable for testing. The
process is relatively simple and can yield results in as little as
twenty-four hours. The PCR method, however, is less statistically
precise. Further, if the PCR method is not carefully performed, it
is more susceptible to contamination than the RFLP method. See id.
at 440; George Bundy Smith & Janet A. Gordon, The Admission of DNA
Evidence in State & Federal Courts, 65 Fordham L. Rev. 2465, 2471-72
(May 1997); Thomas M. Fleming, Annotation, Admissibility of DNA
Identification Evidence, 84 A.L.R.4th 313, 320-25 (1991).
II
The admission of expert testimony regarding scientific and
technical evidence is governed by Tenn. R. Evid. 702 and 703.
McDaniel v. CSX Transportation, Inc., No. 01-S-01-9605-CV-00095
(Tenn. Sept. 29, 1997).9 Questions regarding the admissibility,
9
McDaniel held that the pre-Rules of Evidence test of Frye v.
United States, 293 F. 1013 (D.C. Cir. 1923), which required that
scientific evidence be generally accepted in the particular field to
which it belonged in order for it to be admissible, was superseded
by the adoption of Tennessee Rules of Evidence 702 and 703.
9
qualifications, relevancy and competency of expert testimony are
left to the discretion of the trial court, whose ruling will not be
overturned in the absence of abuse or arbitrary exercise of
discretion. Ballard, 855 S.W.2d at 562. In McDaniel, we
promulgated the principles for the trial court’s guidance in
deciding whether to admit scientific or technical evidence.
First, the evidence must be relevant to a fact at issue in
the case. Tenn. R. Evid. 401, 402. Second, the expert must be
qualified by specialized knowledge, skill, experience, training, or
education in the field of expertise, and the testimony in question
must substantially assist the trier of fact to understand the
evidence or determine a fact in issue. Tenn. R. Evid. 702;
McDaniel, slip op. at 14; see also Otis v. Cambridge Mutual Fire
Ins. Co., 850 S.W.2d 439, 443 (Tenn. 1992). Finally, when the
expert witness offers an opinion or states an inference, the
underlying facts or data upon which the expert relied must be
trustworthy. Tenn. R. Evid. 703; McDaniel, slip op. at 14.
Simply put, scientific or technical evidence will not be
admissible unless it is determined to be reliable. The reliability
of scientific evidence is determined by considering the following
nonexclusive list of factors:
1. Whether the scientific
evidence has been tested and the
methodology with which it has been
tested;
McDaniel, slip op. at 16.
10
2. Whether the evidence has
been subjected to peer review or
publication;
3. Whether a potential rate of
error is known;
4. Whether, as formerly
required by Frye, the evidence is
generally accepted in the scientific
community; and
5. Whether the expert’s
research in the field has been
conducted independent of litigation.

III
Richard Guerrieri, a forensic scientist with Roche
Biomedical Laboratories, testified as a State’s witness regarding
the results of the PCR analysis. During a jury-out hearing,
Guerrieri testified that he had a Master of Science degree in
Forensic Chemistry and a Bachelor of Science degree in Biology, with
course work equivalent to a similar degree in Chemistry. He had
worked in the field of forensic science for fifteen years, with the
most recent six years devoted to DNA analysis. During that time, he
had worked hundreds of cases with thousands of samples. He had
testified as an expert in forensic science between eighty and ninety
times and as an expert in DNA analysis approximately thirty of those
times. He had only testified on one prior occasion regarding DNA
11
analysis using the PCR method. The rest of his experience in
testifying about DNA was in cases where the RFLP method was used.
Despite his limited experience in testifying on the PCR
method of DNA analysis, he testified that it was recognized and
accepted in the scientific community and had been admitted into
evidence in twenty to thirty states.10 He was aware of many
publications that had discussed the validity of the PCR method.
Guerrieri admitted that no DNA analysis can establish identity to an
absolute certainty. The available methods are tests of exclusion;
they are designed to determine whether a person can be excluded as
the source of the unidentified evidence.
The trial court found Guerrieri qualified as an expert and
ruled that he could testify regarding the results of the PCR
analysis. Guerrieri then testified that the victim’s DNA is type
“1.2, 1.2,” a type shared by 6.5% of the black population. The
defendant’s DNA is type “4, 4,” a type shared by 9.8% of the black
population.11
Guerrieri further testified that the PCR analysis of spots
on the defendant’s clothing resulted in the detection of a mixture
of type 1.2 and type 4 DNA. Because of the differing intensity of
the two types found on the defendant’s clothing, Guerrieri opined
10
Guerrieri also testified that based on his communications with
FBI personnel, he was under the impression that the PCR method had
been admitted in Tennessee courts. However, this Court is not aware
of any appellate cases in Tennessee addressing this issue.
11
Apparently both the defendant and the victim are black
Americans.
12
that they most likely originated from two different persons, a “1.2,
1.2” type and a “4, 4” type. Nevertheless, 18% of the black
population do have the combination “1.2, 4” type of DNA.
IV
The Legislature has determined that DNA analysis is a
trustworthy and reliable method of identifying characteristics in an
individual's genetic material and will be admissible so long as it
otherwise meets the requirements of the Tennessee Rules of Evidence.
Tenn. Code Ann. § 24-7-117(b)(1) (Supp. 1991). The Legislature
evidently enacted this statute in order to ease the admission of DNA
evidence in Tennessee. Neil P. Cohen, et al., Tennessee Law of
Evidence § 401.34, at 147 (3d ed. 1995). Even before Tenn. Code
Ann. § 24-7-117 was enacted, Tennessee courts recognized the
reliability and trustworthiness of DNA evidence. See State v.
Harris, 866 S.W.2d 583, 587 (Tenn. Crim. App. 1992) (Harris
violation occurred in 1989, before the effective date of the
statute).
Tennessee Code Annotated § 24-7-117(a) defines “DNA
analysis” as the process of analyzing and comparing DNA for
identification purposes. The defendant asserts that the PCR method
of DNA analysis is a method of exclusion, not identification, and as
such is not governed by Tenn. Code Ann. § 24-7-117. Additionally,
the defendant claims the PCR method’s reliability has not been
adequately established. We find this argument without merit. At
the time the statute was passed, the DNA “method of choice” was the
13
RFLP method, which, like the PCR method, is not definitive in
identifying a particular person. Nevertheless, the RFLP method has
clearly been considered by the courts to be a method of
identification. See, e.g., State v. Edwards, 868 S.W.2d 682, 697
(Tenn. Crim. App. 1993); Harris, 866 S.W.2d at 386; State v.
Gregory, 862 S.W.2d 574, 576 (Tenn. Crim. App. 1993). While the PCR
and RFLP methods of DNA analysis can be characterized as tests of
exclusion, there are nevertheless relevant to the identification of
the perpetrator of a crime. Because the results of the PCR method
of DNA analysis are relevant to identification, the PCR method falls
under the § 24-7-117(a) definition of “DNA analysis.”
Under the McDaniel analysis of the admissibility of
scientific evidence, the initial question is whether the results of
the PCR analysis are relevant under Tenn. R. Evid. 401. We conclude
that they are. The discovery of DNA consistent with the victim’s
DNA, but inconsistent with the defendant’s DNA, on the defendant’s
clothing is relevant because it tends to identify the defendant as
the assailant. The results of the PCR method of DNA analysis may
not be as probative as that of the RFLP method, because the PCR
method results in a large pool of possible DNA contributors, instead
of the infinitesimally small number resulting from the RFLP method.
Under the results of the PCR analysis here, 6.5% of the entire black
population have the victim’s DNA type, and 18% of the same
population have a combination of the victim’s and defendant’s DNA
type. Yet, the PCR method of DNA analysis, while not as specific as
the RFLP method, serves by process of elimination to increase the
probability of an identification and thus is relevant.
14
The next question under the McDaniel analysis is whether
the witness was qualified as an expert by knowledge, skill,
experience, training, or education and whether the witness’
specialized knowledge substantially assisted the trier of fact to
understand the evidence or to determine a fact in issue. Tenn. R.
Evid. 702. The expert witness, Guerrieri, was extensively
qualified, by both education and experience, in the field of DNA
testing. Furthermore, Guerrieri substantially assisted the jury to
properly understand the complex DNA evidence. He clearly explained
the process and results of the PCR analysis, without overstating the
conclusiveness of the evidence. We conclude that the requirements
of Rule 702 are satisfied.
Next, under McDaniel and Tenn. R. Evid. 703 the facts or
data relied upon by an expert in giving his or her opinion must be
trustworthy and reliable. Because the DNA evidence at issue here is
governed by Tenn. Code Ann. § 24-7-117, the evidence is statutorily
regarded as trustworthy and reliable. Tennessee Code Annotated §
24-7-117 exempts DNA evidence from the trial court determination
under Rule 703 of whether it provides a trustworthy and reliable
method of identifying characteristics in an individual’s genetic
material. Consequently, a judicial determination of the scientific
reliability of the evidence is unnecessary.
Nevertheless, this Court finds the PCR method of DNA
analysis an inherently trustworthy and reliable method of
identification. In doing so, we join a number of other state and
federal jurisdictions that have already recognized the reliability
15
and admissibility of evidence based on the PCR method.12 Several
factors support our finding. First, the PCR method of DNA analysis
has been subjected to extensive peer review. One court has
estimated that over four thousand published scientific articles
exist addressing the merits of the method. State v. Lyons, 924 P.2d
at 813. Second, the PCR method is considered reliable and error-
free, as long as protocols and controls are utilized. Id. at 812.
With respect to acceptance of the PCR method by the scientific
community:
In 1992, the National Research
Council noted that “[t]he theory of
PCR analysis . . . is scientifically
accepted and has been accepted by a
number of courts.” In 1996, the
National Research Council reported

16
that “[t]he technology for DNA
profiling and the methods for
estimating frequencies and related
statistics have progressed to the
point where the reliability and
validity of properly collected and
analyzed DNA data should not be in
doubt.”
Id. at 812, n.22 (citations omitted). Thus, the PCR method is
generally accepted in the scientific community as a valid means for
identifying unknown contributors of body tissue/fluid samples.
Finally, Guerrieri testified that he spent extensive time developing
and validating DNA testing methods, independent of any litigation.
Hereafter, the PCR method of DNA analysis shall be
admissible into evidence without antecedent expert testimony as to
its trustworthiness and reliability, pursuant to Tenn. Code Ann. §
24-7-117(b)(1). As provided by that statute, parties are
nevertheless allowed to offer proof that DNA analysis is not
trustworthy and reliable. Tenn. Code Ann. § 24-7-117(b)(2). For
example, a party can challenge the reliability of a particular test
in any given case by a showing of sloppy handling of samples,
failure to train the personnel performing the testing, failure to
follow protocol, and the like.13 Such a challenge, however, will go
to the weight, not the admissibility, of DNA evidence.
We hold that the trial court's admission of the evidence
related to the Polymerase Chain Reactive method of DNA analysis was
not an abuse of discretion. Accordingly, the judgment of the Court
13
The defendant did not raise any issue concerning the manner
in which the specimen was handled or the test performed.
17
of Criminal Appeals is affirmed. Costs of this cause are taxed to
Begley for which execution may issue if necessary.
