Polymerase chain reaction (PCR) is used to amplify nucleic acids. It was invented in its current form by Kary Mullins in 1983/1986.
The template (DNA or RNA) is duplicated by a thermostable DNA polymerase - originally from Thermus aquaticus - using sequence specific primers (short single-strand oligonucleotides) that are designed to sit on either side of the piece of template that is to be amplified.
Changes in temperature are used to move through the different stages required to duplicate the DNA.
Each cycle duplicates the template, meaning an exponential increase in the amount of the target sequence. Usually, 30 cycles produce sufficient DNA for downstream applications. More cycles may produce more, but at some point the enzyme becomes less efficient or the dNTPs run out.
An example of polymerase chain reaction (PCR) is the process of amplifying a specific segment of DNA in a laboratory setting. PCR involves cycling through three key temperature phases - denaturation, annealing, and extension - to replicate the DNA segment of interest in a test tube. This technique is widely used in research, diagnostics, and forensic analysis.
Polymerase chain reaction
The polymerase used in polymerase chain reaction (PCR) is typically derived from a thermophilic bacterium called Thermus aquaticus. The specific polymerase most commonly used is Taq polymerase, which is known for its ability to withstand high temperatures required for PCR.

polymerase chain reaction
To bring about a polymerase chain reaction DNA sequences are placed in .2-.5ml reaction tubes and then placed in a thermal cycler. To achieve the reaction the sequences must undergo 20-40 temperature changes.
