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.

Mar 26, 2025 · The polymerase chain reaction enables investigators to obtain the large quantities of DNA that are required for various experiments and procedures in molecular biology, forensic analysis, evolutionary biology, and medical diagnostics.

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.

Jan 21, 2025 · A PCR (polymerase chain reaction) test is a lab technique that amplifies (creates more copies) of genetic material (DNA). Healthcare providers can use PCR to test for infectious diseases, to look for genetic changes in tumors or to diagnose genetic diseases.

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.

Sep 2, 2022 · The most widely used target nucleic acid amplification method is the polymerase chain reaction (PCR). This method combines the principles of complementary nucleic acid hybridization with those of nucleic acid replication applied repeatedly through numerous cycles.

PCR is a very sensitive technique that allows rapid amplification of a specific segment of DNA. PCR makes billions of copies of a specific DNA fragment or gene, which allows detection and identification of gene sequences using visual techniques based on size and charge.

May 31, 2022 · Sometimes called molecular photocopying, conventional polymerase chain reaction (PCR) is a technique used to amplify (replicate) trace amounts of DNA and RNA from a sample. A PCR thermal cycler is used to produce the large amounts required for research.

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.

Among these methods, Polymerase Chain Reaction (PCR) has generated great benefits and allowed scientific advancements. PCR is an excellent technique for the rapid detection of pathogens, including those difficult to culture.
