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. 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.
polymerase chain reaction. most widely used amplification technique enables researchers to produce millions of copies of a specific DNA sequence in approximately two hours. in nature, msot organisms copy their DNA in the same way. The PCR mimics this process, only it does it in a test tube. Polymerase chain reactions (PCR) are what allow for small samples of DNA to replicate numerous times and eventually become plentiful enough for proper analysis. PCR is useful … in DNA fingerprinting as they provide a quick and efficient way to replicate DNA. In the simplest form of PCR, there are two types of primers used:   The forward primer   The reverse primer. Edit. Share to: 1  Replace a worn bicycle chain A bicycle chain is always exposed to the elements. Best Answer: PCR stands for polymerase chain reaction. PCR is a process that is done to take a little bit of DNA as well as the enzyme DNA polymerase and amplify (increase) the DNA sample. In short, it's a way to make more DNA from a small sample. Source(s): tigerbyte16 · 7 years ago. 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 first nucleotide. The polymerase chain reaction (PCR) is a technique widely used in molecular biology. It derives its name from one of its key components, a DNA polymerase used to amplify a piece of DNA by in vitro enzymatic replication. As PCR progresses, the DNA thus generated is itself used as a template for replication. PCR is a process that is done to take a little bit of DNA as well as the enzyme DNA polymerase and amplify (increase) the DNA sample. In short, it's a way to make more DNA from a small sample. Source(s): tigerbyte16 · 7 years ago. PCR amplifies a specific region of a DNA strand (the DNA target). Most PCR methods typically amplify DNA fragments of between 0.1 and 10 kilo base pairs (kbp), although some techniques allow for amplification of fragments up to 40 kbp in size. 1 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). Kary Mullis explains how the polymerase chain reaction (PCR) was named. SOURCE: DNAi. 15924. Making many copies of DNA. Polymerase chain reaction (PCR) enables researchers to produce millions of copies of a specific DNA sequence in approximately two hours. This automated process bypasses the need to use bacteria for amplifying DNA.  The polymerase chain reaction (PCR) is used to amplify DNA samples so there are enough copies present to do further experiments. In the simplest form of PCR, there are two types of primers used:   The forward primer   The reverse primer. Edit. Share to: 1  Replace a worn bicycle chain A bicycle chain is always exposed to the elements. PCR (polymerase chain reaction) is a method to analyze a 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. Previously, amplification of DNA involved cloning the segments of interest into vectors for expression in bacteria, and took weeks. But now, with PCR done in test tubes, it takes only a few hours 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. 1 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).
