PCR Part 1

2024年12月30日

PCR is based on three simple steps required for any DNA synthesis reaction: (1) denaturation of the template into single strands; (2) annealing of primers to each original strand for new strand synthesis; and (3) extension of the new DNA strands from the primers.

Assembly PCR – longer DNA fragments are aplified by using overlapping primers. Asymmetric PCR – only one strand of the target DNA is amplified. In situ PCR – PCR that takes place in cells, or in fixed tissue on a slide.
