WebbPCR involves a process of heating and cooling called thermal cycling which is carried out by machine. There are three main stages: Denaturing – when the double-stranded template DNA is heated to separate it into two single strands. Annealing – when the temperature is lowered to enable the DNA primers to attach to the template DNA. Webb9 apr. 2024 · Extension: The final PCR step is when the DNA polymerase enzyme reads the template and connects new nucleotides to the primer’s 3’ end, extending a new complementary strand of DNA (Figure 5). Completion of the final step and the first cycle of PCR, will make two double stranded DNA copies from the original template DNA, …
