Biotechnology companies sell kits that allow you to do PCR to amplify STR regions from human blood samples that you have collected. What components would you expect to find in the kit in order to be able to do successful PCR reactions?

Question

Quizplus · Accepted Answer

PCR requires a heat-stable DNA polymerase (like Taq polymerase) to withstand the high temperatures of the denaturation step, primers that flank the target STR regions to initiate DNA synthesis, and free nucleotides to build the new DNA strands.
