Polymerase Chain Reaction (PCR) is a powerful molecular biology technique used to amplify specific DNA sequences. It enables researchers and clinicians to generate millions of copies from a small DNA sample, making it essential for diagnostics, genetic research, and forensic analysis. https://www.tripoto.com/trip/polymerase-chain-reaction-pcr-the-cornerstone-of-modern-molecular-biology-3e45006451091c73
