Polymerase Chain Reaction (PCR) is a cutting-edge biotechnology technique that has revolutionized the world of molecular biology and genetics It is used for amplifying and analyzing DNA and makes it possible to look at genetic data in extremely small amounts of tissue or fluids.
PCR involves a three-step cycle of heating and cooling the DNA sample which causes it to replicate. During each cycle, the enzymes called polymerases, attach to the sections of the DNA strand which contain the genetic information and cause it to duplicate. This process is repeated until the desired amount of DNA has been produced. Despite its complexity, PCR is incredibly reliable and accurate, allowing scientists to obtain reliable data quicker and more cheaply than ever before.
