WebThis cycle repeats 25 25 - 35 35 times in a typical PCR reaction, which generally takes 2 2 - 4 4 hours, depending on the length of the DNA region being copied. If the reaction is efficient (works well), the target region can go from just one or a few copies to billions. WebMar 16, 2015 · A gene is a string of DNA that encodes the information necessary to make a protein, which then goes on to perform some function within our cells. After the Human Genome Project, scientists found that there were around 20,000 genes within the genome, a number that some researchers had already predicted. inceptua gmbh berlin
