1. We've discussed many different kinds of polymerases over the last several weeks, including RNA polymerases for transcription, DNA polymerases for replication, primase, Taq DNA polymerase for PCR, and telomerase for telomere extension (and there are many others!). Each has their own unique functions and limitations. What are their similarities and differences? How can comparing and contrasting among them help you deepen your understanding of each system and also of the relationships about the systems?.
