(1) DNA replication is a method of growth, repair, and recovery. Give me the highlights for a cell making nuclear copies and for cells dividing for reproductive purposes. Not too much detail, because this could get lengthy. I will ask for more depth if I feel you did not cover the topic enough.
(2) Ever notice how presumptive testing uses mainly protein markers while DNA testing does not? You know that DNA is the start and proteins are the result. Explain the role of RNA and give an example of how this supportive polymer could be used in the forensic field.
(3) The first topic this week discussed harnessing the machinery already in place naturally to use for our purposes. So, what is required for PCR and what components of the natural process of replication are we artificially mimicking? As an example, the primers we use in the reaction mimic the ability of the body to select which portion of DNA is replicated. What do the following mimic: Buffer, Taq polymerase. Magnesium. AID any other components you wish.
