Question

Quizplus · Accepted Answer

The polymerase chain reaction (PCR) is a technique used to amplify small amounts of DNA into larger quantities. PCR has become an integral part of DNA fingerprinting, which is a forensic technique used to identify individuals based on their DNA profiles. PCR is used to amplify specific regions of an individual's DNA, which can then be compared to other individuals' DNA profiles to determine identity. PCR is not involved in preparing recombinant DNA, transcription, translation, or replication.
