Polymerase chain reaction (PCR) is a method for amplifying very small DNA amounts located on any material, solid or liquid. It is important to appreciate the fact that every living being contains sequences of DNA that are unique to not only their species but to the individual member of the species. Scientists studying the DNA sequence can do so even more easily even if the DNA sample is very scanty because by employing the PCR technique it permits the making of countless identical copies of the sequence so that they can determine with more certainty the identity of the DNA source. The Process of DNA Matching  The process of identification may start with PCR amplification if the original material containing the DNA sequence is not enough to permit proper testing. Once the desired DNA sequence has been amplified by the PCR process, the amplified segments then have to be compared...
