Several Advancements in technology produced a fast DNA sequencer in the 70’s, and in 1983, Karv Mullis created what is called Polymerase Chain Reaction (PCR). PCR is a very simple and inexpensive technology that is used to amplify and produce large amounts of copies of a segment of DNA. Now this has become one of the most significant scientific advances in molecular biology, PCR amplification is used every day to diagnose diseases, its also used to identify bacteria and viruses, and to match criminals to crime scenes. PCR has revolutionized the study of DNA to such an extent that Dr. Mullis was awarded the Nobel Prize in Chemistry in 1993.
