Pcr final elongation

SpletIn a typical PCR reaction, the cycle is repeated 25-40 times and takes approximately 2-4 hours, depending on the length of DNA needing to be copied (see image below). The reason for this is that after the first cycle, it is no longer only the original DNA template that is being used for amplification, but also the new strands that are used in ...
