The steps to be followed for the PCR procedure are:
<em>Denaturation</em>
Option 1. Involves incubation at 94°C to denature DNA strands into single strands by breaking of weak hydrogen links
<em>Annealing</em>
Option 3. Temperature is lowered to 60°C to allow primers joining their similar DNA sequences.
<em>Elongation</em>
Option 2. Incubate at 72°C to promote the extension of the DNA strands, actually extending them.
