The polymerase chain reaction (PCR) is a technique used amplify multiple copies of specific DNA sequences. It was developed in 1983 by Kary Mullis and is now one of the most widely used techniques in the biological sciences (even I use it). PCR provides scientists with a large quantity of pure DNA, allowing scientists to perform DNA analysis even with tiny amounts of genetic material. In additional to scientific pursuits, PCR is also applied to the diagnosis of diseases and DNA-fingerprinting, so its has also made a significant contribution in the fight against illness and crime.
This is a music video made by a company that develops equipment for procedures such as PCR, which humorously highlights how thankful scientists are for this technique.
