Question

Quizplus · Accepted Answer

PCR (Polymerase Chain Reaction) is a technique used to amplify or make many copies of a specific DNA segment. While it can rapidly and cheaply make billions of copies of a gene from a small amount of DNA, it does not sequence the bases within a gene as it is being copied. DNA sequencing is a separate process.
