Short sequences called primers are used to selectively amplify a specific DNA sequence. PCR was invented in the s and is now used in a variety of ways, including DNA fingerprinting, diagnosing genetic disorders and detecting bacteria or viruses. Because molecular жмите сюда genetic analyses require significant amounts of a DNA sample, it is nearly impossible for researchers to study isolated pieces of genetic material without PCR amplification. This how long covid pcr test results adds fluorescent dyes to the PCR process to measure the amount of genetic material in a sample. The testing process begins when healthcare workers collect samples using a nasal swab or saliva tube. The two DNA template strands are then se
