Polymerase chain reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro (in a test tube rather than an organism). PCR relies on a thermostable DNA polymerase, Taq polymerase, and requires DNA primers designed specifically for the DNA region of interest. The Polymerase Chain Reaction (PCR) is an important tool for many applications. For example, it can be used to amplify a sample of DNA when there isn't enough to analyze (e.g. a sample of DNA from a crime scene, archeological samples), as a method of identifying a gene of interest, or to test for disease.
