WebbIn vitro, we cannot replicate all of the biological intricacies that occur in the nucleus of a cell, however, we do know that under extreme heat, that the double helix will break apart. Therefore, the first step of the PCR reaction is to subject the DNA to extreme heat (95°C/ 203°F) to break apart the two strands forming the template DNA. 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.
