The PCR stands for polymerase chain reaction.
This biotechnological tool is used to amplify the template DNA strand.
This technique requires thermostable DNA polymerase that remains stable at high temperatures.
Taq polymerase is one such enzyme that is used in PCR.
The reaction involves three steps:
Denaturation – at a very high temperature of 95℃, DNA template denatures to form single stranded DNA strands.
Annealing – The specific primers bind to these DNA templates. The temperature depends on the melting temperature of primers.
Extension- The process where the primers extend by adding dNTPs.
Final Answer:
The full form of PCR is polymerase chain reaction and is used to amplify a particular DNA strand.
