<p style="color:#000000">2. Three serial dilutions were conducted, yielding concentrations of 1:10, 1:100, and 1:1000. This was carried out in order to find the optimum concentration of template DNA to use, as we didn't know the concentration yielded from the Miniprep Protocol used to extract the plasmid. We conducted a gradient cycle because even though we knew the annealing temperatures of the primers we'd designed, we wanted to make sure we had the optimum temperature range.</p>
