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.

Jan 17, 2025 · PCR is used to diagnose genetic disease and to detect low levels of viral infection. In forensic medicine it is used to analyze minute traces of blood and other tissues in order to identify the donor by his genetic “fingerprint.”

Jan 29, 2024 · Health experts can use PCR tests as a quick, accurate way to diagnose infectious diseases, spot genetic changes that can cause disease, and identify small amounts of cancer cells.

Aug 17, 2020 · Sometimes called "molecular photocopying," the polymerase chain reaction (PCR) is a fast and inexpensive technique used to "amplify" - copy - small segments of DNA. Because significant amounts of a sample of DNA are necessary for molecular and genetic analyses, studies of isolated pieces of DNA are nearly impossible without PCR amplification.

Mar 6, 2023 · The polymerase chain reaction (PCR) is a laboratory nucleic acid amplification technique used to denature and renature short segments of DNA using DNA polymerase I enzyme, an isolate from Thermus aquaticus, known as Taq polymerase.[1][2] In 1985, PCR was introduced by Mullis et al, who were later awarded the Nobel Prize for their work.[3]

Jan 21, 2025 · What is a PCR test? A PCR (polymerase chain reaction) test is a way to look for genetic material (DNA or RNA). After taking a body fluid sample (like blood) or a swab from a body site (like deep in your nose), scientists use PCR to make many copies of DNA (amplification) that was in the original sample.

Sep 2, 2022 · PCR is an enzymatic process in which a specific region of DNA is replicated over and over again to yield many copies of a particular sequence. The most widely used target nucleic acid amplification method is the polymerase chain reaction (PCR).

Aug 3, 2023 · Polymerase chain reaction (PCR) is a nucleic acid amplification technique used to amplify the DNA or RNA in vitro enzymatically.

PCR or Polymerase Chain Reaction is a technique used in molecular biology to create several copies of a certain DNA segment. This technique was developed in 1983 by Kary Mullis, an American biochemist. PCR has made it possible to generate millions of copies of …

Aug 10, 2022 · Polymerase Chain Reaction (PCR) is a powerful method for amplifying particular segments of DNA, distinct from cloning and propagation within the host cell. This procedure is carried out entirely biochemically, that is, in vitro. PCR was invented by Kary Mullis in 1983. He shared the Nobel Prize in chemistry with Michael Smith in 1993.
