Taq polymerase is an enzyme that is used by scientists in the polymerase chain reaction because it is stable at high temperatures. It is the polymerase used by a bacteria, Thermus auquatics, which lives in hot springs,
Large amounts of a sample of DNA are necessary for molecular and genetic analyses, and the polymerase chain reaction is used to amplify very small amounts of DNA. It is quick and a fairly cheap process. It was created by Kary Mullins in 1993 and can create more than one billion exact copies of the original DNA segment in a few hours. The Human Genome Project relied heavily on the polymerase chain reaction technique.
