0The polymerase chain reaction (PCR) was originally developed in 1983 by the American biochemist Kary Mullis.
-
PCR is used in molecular biology to make many copies of (amplify) small sections of DNA.
-
Using PCR it is possible to generate thousands to millions of copies of a particular section of DNA from a very small amount of DNA.
-
PCR is a common tool used in medical and biological research labs. It is used in the early stages of processing DNA for sequencing for detecting the presence or absence of a gene to help identify pathogens during infection, and when generating forensic DNA profiles from tiny samples of DNA.
