How many copies are made in pcr

WebThe PCR process was originally developed to amplify short segments of a longer DNA molecule (Saiki et al. 1985). A typical amplification reaction includes target DNA, a thermostable DNA polymerase, two oligonucleotide primers, deoxynucleotide triphosphates (dNTPs), reaction buffer and magnesium. WebAfter completion of one cycle of PCR, two copies of the target DNA are produced both of which serve as a template for the next PCR cycle and produce 4 copies. Hence, there is an …
