How is the amplification of a gene sample of interest carried out using Polymerase Chain Reaction (PCR)?

Polymerase chain reaction (PCR) is the process in which the amplification of the gene of interest is carried out with two sets of primers and a thermostable DNA polymerase enzyme Taq polymerase. The process involves the following steps:
Denaturation: The double-stranded DNA is heated up to 94oC which causes the hydrogen bonds to break and the two strands get separated.
Annealing: The two sets of primers are added which bind to the appropriate complementary segment of DNA strand at 540C.
Extension: The Taq polymerase enzyme polymerizes the nucleotide chain using the nucleotides provided in the medium and by using the template strand at 720C.
