PCR (Polymerase Chain Reaction)

Polymerase Chain Reaction (PCR) is a laboratory technique used to amplify a specific segment of DNA, making millions of copies of it. This process involves repeated cycles of heating and cooling to separate the DNA strands, attach short DNA sequences called primers, and use an enzyme called DNA polymerase to create new DNA strands. PCR is widely used in various fields including genetics, medicine, and forensic science for purposes such as diagnosing diseases, identifying genetic traits, and solving crimes by analyzing DNA samples. Its ability to produce large amounts of DNA quickly makes it a powerful tool in biological research.
