The polymerase chain reaction (PCR) is a biochemical technology in molecular biology to amplify a single 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.

PCR is used for amplyfing DNA, it can be done using single or two or random primers depending on particular requirement.

The PCR is used to magnify/amplify a target DNA. See Forensic applications.

In the PCR techniques when we are making a rxn mix we are adding primers they helps to amplify the our DNA sequence by generating the nucleotides and adding those at a specific position, thats why we are getting the millions of copies of DNA by these oligonucleotide primer sequences.

PCR is used to amplify a specific region of a DNA strand. Its amplify DNA fragments of between 0.1 and 10 kilo base pairs (kb), although some techniques allow for amplification of fragments up to 40 kb in size.

PCR is worked like photostat machine and generate millions DNA xerox in some hours. This method is developed by Kary Mullis in 1985.

By utilising specific primers for desired gene we can amplify the gene of interest in vitro by using a technique called polymerase chain reaction in which we provide all the necessary components like pcr buffer, dna polymerase enzyme, primers and final and most important factor temperature.

DNA polymerases can only extend a sequence(that is primer.)they cannot start the process of replication.They can add nucleotides at 3' end of growing strand.This is why primers are used.

PCR is used to amplify dna segment. It has many application in our life so also known as people choice reaction.

This method is developed by kary mullis. It is used to amplify a particular DNA segment. It involves denaturation, annealing.
