Question

Quizplus · Accepted Answer

The polymerase chain reaction (PCR) is a technique used to amplify specific sections of DNA. It is useful in molecular biology research and diagnostics, allowing for the rapid production of large quantities of DNA for analysis. PCR involves a series of cycles that denature DNA, anneal primers, and extend new strands using a DNA polymerase enzyme. By using specific primers that target a particular region of DNA, PCR can amplify only the desired segment, allowing for further analysis or cloning.
