Polymerase chain reaction (PCR) is a method widely used in molecular biology to make many copies of a specific DNA segment. Using PCR, copies of DNA sequences are exponentially amplified to generate thousands to millions of more copies of that particular DNA segment.

Polymerase chain reaction definition is - an in vitro technique for rapidly synthesizing large quantities of a given DNA segment that involves separating the DNA into its two complementary strands, using DNA polymerase to synthesize two-stranded DNA from each single strand, and repeating the process —abbreviation PCR.
polymerase [pah-lim´er-ās] an enzyme that catalyzes polymerization. polymerase chain reaction a rapid technique for in vitro amplification of specific DNA or RNA sequences, allowing small quantities of short sequences to be analyzed without cloning. pol·ym·er·ase chain re·ac·tion (PCR), an enzymatic method for the repeated copying of the two ...
Polymerase chain reaction ( PCR), a technique used to make numerous copies of a specific segment of DNA quickly and accurately. The polymerase chain reaction enables investigators to obtain the large quantities of DNA that are required for various experiments and procedures in molecular biology, ...
Polymerase Chain Reaction (PCR) Introduction PCR (Polymerase Chain Reaction) is a revolutionary method developed by Kary Mullis in the 1980s. PCR is based on using the ability of DNA polymerase to synthesize new strand of DNA complementary to the offered template strand. Because DNA polymerase can add a nucleotide only onto a preexisting 3'-OH group, it needs a primer to which it can add the ....
RT-PCR (Reverse transcriptase-polymerase chain reaction) is a highly sensitive technique for the detection and quantitation of mRNA (messenger RNA). The technique consists of two parts: The synthesis of cDNA (complementary DNA) from RNA by reverse transcription (RT) and ; The amplification of a specific cDNA by the polymerase chain reaction (PCR).

Lesson Summary. Polymerase chain reaction, or PCR, is a laboratory procedure used to make multiple copies of the same piece of DNA.It is conducted in a test tube, Where DNA or template DNA is ...
Polymerase chain reaction allows these pieces of DNA to be amplified so they can be detected. Polymerase chain reaction may be used to look for certain changes in a gene or chromosome, which may help find and diagnose a genetic condition or a disease, such as cancer.
PCR (polymerase chain reaction): PCR (polymerase chain reaction): PCR (polymerase chain reaction) is a technique in molecular genetics that permits the analysis of any short sequence of DNA (or RNA) even in samples containing only minute quantities of DNA or RNA.PCR is used to reproduce (amplify) selected sections of DNA or RNA for analysis.
