PCR principle:

The essence of PCR technology is nucleic acid amplification in vitro, heat to uncoil double stranded DNA, hybridize primer with template DNA at annealing temperature, extend primer in the presence of Taq DNA polymerase, dNTPs, Mg2+ and suitable pH buffer, repeat the process of "denaturation → annealing → primer extension" to 25 ~ 40 cycles. Exponentially expand the nucleic acid copy number in the sample to be tested.
