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

For successful PCR reactions, especially when amplifying STR regions from human blood samples, the kit must contain a heat-stable DNA polymerase (to withstand the high temperatures used during denaturation), primers that specifically flank the STR regions of interest (to ensure the correct DNA segments are amplified), and free nucleotides (dNTPs) to serve as the building blocks for the new DNA strands.
