What is PCR (polymerase chain reaction)? Polymerase chain reaction (PCR) is a technique that is used to amplify trace amounts of DNA (and in some instances, RNA) located in or on almost any liquid or surface where DNA strands may be deposited.
Therefore, the PCR technology is widely used in both the DNA research and testing fields. The PCR is commonly carried out in a thermal cycler. The thermal cycler heats and cools the reaction tubes to achieve the temperatures required at each step of the reaction. The PCR occurs in the following steps:
