A thermal cycler, also known as a PCR machine, is widely used in molecular biology for DNA amplification through the Polymerase Chain Reaction (PCR).
It involves:
Denaturation: Heating the DNA to to separate the strands.
Annealing: Cooling to to allow primers to bind to specific sequences.
Extension: Raising the temperature to for DNA polymerase to synthesize new DNA strands. These cycles are repeated to exponentially amplify the DNA.
