Question

Quizplus · Accepted Answer

Polymerase chain reaction (PCR) is a laboratory technique used to amplify or create billions of copies of a specific DNA segment in a relatively short time. It involves cycles of denaturation, annealing, and extension using DNA polymerase enzyme and specific primers. This technique allows for the rapid and efficient production of DNA copies for various applications, including gene cloning, genetic screening, and forensic analysis.
