Polymerase chain reaction - Wikipedia

WebPolymerase chain reaction (PCR) is a technology for exponential amplification of a fragment of DNA. (The PCR is covered by patents owned by Hoffman-La Roche. A license is required to use the PCR process.) The limit of its sensitivity is a single molecule, making PCR a superb qualitative tool for the specific detection of rare DNA sequences.
