What Does PCR Stand For?

PCR stands for Polymerase Chain Reaction

Polymerase Chain Reaction (PCR) is a widely used molecular biology technique that allows for the amplification of specific DNA sequences. By cycling through a series of temperature changes, PCR facilitates the denaturation of DNA, annealing of primers to target sequences, and elongation of new DNA strands by a DNA polymerase enzyme. This process enables the generation of millions of copies of a DNA segment from a small initial sample, making it an essential tool for applications in genetic research, medical diagnostics, forensic analysis, and more.
