You are always looking for an opportunity to investigate the unknown, to use and show your mental abilities, to find the purpose and meaning of life. You want to grow wise and to understand people and things.
Typically, PCR consists of usually 20-40 repeated temperature changes, called cycles, where each cycles usually contains three steps. It is necessary to perform many cycles because that way the end results will consist mainly of the desired DNA.
Each complete cycle doubles the amount of DNA present, so in just 20 cycles there are over one million (2 20) copies of that specific segment of DNA. For PCR there are five chemical components needed, including a DNA template, DNA polymerase enzyme, primers, nucleotides and reaction buffer.These are described here in detail.here are two requirements for a suitable DNA polymerase enzyme for PCR. First, one is needed that has a good activity rate around 75Â°C. Second, it should be able to withstand temperatures of 95-100Â°C so that more enzyme does not have to be added at the beginning of each new cycle.
