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.
