Quizplus · Accepted Answer

Polymerase chain reaction (PCR) is a technique that can rapidly make millions to billions of copies of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it to a large enough amount to study in detail. This includes making large numbers of copies quickly, making virtually unlimited copies, and requiring very little starting material.
