Which of the following is the correct sequence of PCR?

Explanation

Polymerase chain Reaction The polymerase chain reaction is a method widely used to rapidly make millions to billions of copies of a specific DNA sample in a short period. Process PCR involves using short synthetic DNA fragments called primers to select a segment of the genome to be amplified, and then multiple rounds of DNA synthesis to amplify that segment. The process has 4 steps in total. Sequence The correct sequence of PCR is Heating it breaks the double-stranded structure Cooling Adding the primer which then annealed to make a copy of the strand. Opt A is the right choice here.
