... denaturation and involves heating the samples to about 95°C, which causes the hydrogen bonds between the base pairs to break, allowing the DNA strands to separate. The next step is called annealing. The samples are cooled to about 55°C, which allows the primers to bind to the single-stranded DNA. The primers...
