It enables DNA templates to be exponentially amplified in vitro through cyclic heating and cooling processes. In the PCR process, the template DNA is denatured into single-stranded DNA at high temperatures, and then at low temperatures, primers bind to complementary single-stranded DNA. DNA polymerase starts synthesizing the complementary chain from the primers. As the PCR cycle proceeds, the DNA chains are continuously replicated, ultimately yielding a large quantity of specific DNA fragments.  Plasm technology requires strict temperature control during the experimental process."}]}],"pr":"37b18918b82b9eb55ace152f9d38c4b17c4b9d3f38d941b2c97de37bf339a817"}
