The polymerase chain reaction (PCR) is a technology in molecular biology used to amplify a single copy or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence. If the genomic DNA sequence of a gene is known, RT-PCR can be used to map the location of exons and introns in the gene. 2  The 5' end of a gene (corresponding to the transcription start site) is typically identified by RACE-PCR (Rapid Amplification of cDNA Ends).
Polymerase Chain Reaction (PCR). PCR is a laboratory method used for making a very large number of copies of short sections of DNA from a very small sample of genetic material. This process is called amplifying the DNA and it enables specific genes of interest to be detected or measured.his method is used to measure the amount of DNA that is present in a sample. RT â PCR (Reverse Transcriptase PCR). This method uses PCR to amplify RNA. RNA is a single stranded nucleic acid molecule and needs to be made into DNA before it can be amplified.
