What is PCR (polymerase chain reaction)?

What is PCR?

• The polymerase chain reaction (PCR) was originally developed in 1983 by the American biochemist Kary Mullis. He was awarded the Nobel Prize in Chemistry in 1993 for his pioneering work.
• PCR is used in molecular biology to make many copies of (amplify) small sections of DNA or a gene.
• 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.
