PCR: Steps Involved in Polymerase Chain Reaction - Study.com

WebIt is required for DNA replication because the enzymes that catalyze this process, DNA polymerases, can only add new nucleotides to an existing strand of DNA (it needs a 3' OH to attach to). The polymerase starts replication at the 3'-end of the primer, and copies the opposite strand. In most cases of natural DNA replication, the primer for DNA ... WebSep 17, 2024 · Polymerase Chain Reaction (PCR) has three major steps. Denaturation (strand separation): The separation of the two hydrogen-bonded complementary chains of DNA into a pair of single-stranded polynucleotide molecules by a process of heating (94°C to 96°C) Annealing (primer binding): The temperature is lowered (45-60 °C) so the …
