Polymerase Chain Reaction (PCR)
Polymerase chain reaction (PCR) is an efficient molecular technique that allows for the amplification of a single or small number of copies of a piece of DNA, quickly producing millions of copies. It is used in a wide range of applications, from genetic studies to medical diagnosis and crime scene investigations. PCR has revolutionized biology, allowing for quick and economical ways to test for and diagnose genetic diseases, uncovering genetic predispositions to disease, or detecting mutations related to drug resistance. Furthermore, PCR allows for gene cloning, mutagenesis and a deeper understanding of the mechanisms of DNA replication.
