WebOct 7, 2024 · Primers are short RNA molecules that act as templates for the starting point of DNA replication. DNA polymerases - synthesize new DNA molecules by adding nucleotides to leading and lagging DNA strands. … WebPCR 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.
