polymerase chain reaction

n. Abbr. PCR
A technique for amplifying DNA sequences in vitro by separating the DNA into two strands and incubating it with oligonucleotide primers and DNA polymerase. It can amplify a specific sequence of DNA as many as one billion times and is important in biotechnology, forensics, medicine, and genetic research.

pol′ymerase chain′ reac`tion

the laboratory production of numerous copies of a gene by separating the two strands of the DNA containing the gene segment, marking its location with a primer, and using a DNA polymerase to assemble a copy alongside each segment and continuously copy the copies. Abbr.: PCR

Polymerase chain reactions (PCRs) were carried out in 25 [micro]L of reaction mixtures buffered with 20 mmol/L Tris-HC1 (pH 8.4), containing 10 ng of genomic DNA, 20 pmol/L of each primer, 1.5 mM Mg[Cl.sub.2], 50 mmol/L KCl, 0.2 mmol/L of each deoxynucleoside triphosphate, and 0.2 U of Taq DNA polymerase (Amersham Biosciences Corp, Piscataway, NJ, USA).
They cover mutagenesis in various microbial backgrounds, polymerase chain reaction mutagenesis, protein evolution mutagenesis, protein structure and function mutagenesis, random mutagenesis, and mutator bacterial strain mutagenesis.
