Question

Quizplus · Accepted Answer

PCR is a technique used to amplify a specific region of DNA. The three main steps involved in PCR are denaturation, primer annealing, and primer extension. These three steps are repeated for multiple cycles to amplify the target DNA. Gene expression is not a part of the PCR process.
