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
