Question

Quizplus · Accepted Answer

The primary purpose of PCR (Polymerase Chain Reaction) is to create billions of copies of a specific segment of DNA. This can be useful in a variety of applications such as DNA sequencing, genetic testing, and research. PCR does not create fragments of different lengths, recombinant DNA, plasmids, or transgenic crop plants (although it may be used in the process of creating these things).
