WebInitially, the DNA template is denatured by heating it to a high temperature, causing the double-stranded DNA to separate into two single strands. Then, small DNA primers are annealed to the target DNA sequence, allowing a heat-stable DNA polymerase enzyme to stretch from the primer and manufacture new DNA strands complementary to the template.
