Definition of PCR PCR or polymerase chain reaction can define as in vitro technique of preparing around million copies of target DNA sequence through consecutive stages of heat denaturation, primer annealing, and primer extension. Asymmetric PCR is a variation of PCR used to preferentially amplify one strand of the original DNA more than the other. PCR can use the smallest sample of the DNA to be cloned and amplify it to millions of copies in just a few hours. In early 2020, CDC developed its first laboratory test kit for use in testing patient specimens for SARS-CoV-2. The polymerase chain reaction is a three step cycling process consisting of defined sets of times and temperatures. Asymmetric PCR differs from regular PCR by the excessive amount of primers for a chosen strand.
