WebMar 6, 2024 · In the third step in the process, the DNA polymerase replicates DNA by extension from the 3’ end of the primer, making a new DNA strand. At the end of the first cycle, there are twice as many DNA molecules, just as in cellular replication. But in PCR, the process is repeated, usually for between 25 and 30 cycles. WebDenaturation is the first step in the PCR reaction. The thermocycler heats up to roughly 95 degrees Celsius, which causes the double-stranded DNA helix to melt open into two single-stranded DNA templates. During the annealing step, the temperature cools between 45-65 degrees Celsius and the single-stranded primers attach to the appropriate ends ... cindy hollen notary nicktown pa
