Chain reaction in chemistry and physics is a process that produces products capable of initiating subsequent processes of a similar nature. It is a self-sustaining sequence in which the resulting products continue to propagate further reactions.
Polymerase Chain Reaction (PCR) is a rapid technique used for in-vitro amplification of DNA by repeatedly replicating a specific target sequence. It involves heating and cooling cycles to denature, anneal primers, and synthesize new DNA strands, allowing for a millionfold amplification of DNA.
Sep 4, 2024 · Kary Mullis was an American biochemist, cowinner of the 1993 Nobel Prize for Chemistry for his invention of the polymerase chain reaction (PCR), a simple technique that allows a specific stretch of DNA to be copied billions of times in a few hours.

The cloning of expressed genes and the polymerase chain reaction (PCR), two biotechnological breakthroughs of the 1970s and 1980s, continue to play significant roles in science today. Both...
The polymerase chain reaction (PCR) is a method widely used to make millions to billions of copies of a specific DNA sample rapidly, allowing scientists to amplify a very small sample of DNA (or a part of it) sufficiently to enable detailed study. PCR was invented in 1983 by American biochemist Kary Mullis at Cetus Corporation.
Jun 7, 2019 · Polymerase chain reaction (PCR) was invented by Mullis in 1983 and patented in 1985. Its principle is based on the use of DNA polymerase which is an in vitro replication of specific DNA sequences.
