WebIntroduction. Polymerase 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 ... WebNew DNA is made by enzymes called DNA polymerases, which require a template and a primer (starter) and synthesize DNA in the 5' to 3' direction. During DNA replication, one new strand (the leading strand) is made as a continuous piece. The other (the lagging strand) is made in small pieces.
