WebWhat 3 steps make up a cycle of PCR, and what happens during each step?: - The 3 steps that make up a cycle of PCR are denature, annealing, and extensions. In denaturing, the double stranded template DNA is heated and separates into two single strands. In annealing, the temperature lowers, and this causes the DNA primers to attach to the ... WebMar 24, 2024 · Primer length. The optimal length of a PCR primer lies between 18 and 24 bp. Longer primers are less efficient during the annealing step, resulting in a lower amount of PCR product. Conversely, shorter primers are less specific during the annealing phase, leading to more non-specific binding and amplification. However, there are exceptions to ...
