2. (3 pts) Would proper termination of transcription in eukaryotes be more likely to be blocked by a mutation that inactivated CstF or polyA polymerase? Explain. Grading: 1 pt for indicating which mutation would be more likely to prevent proper termination. 0.5 pt for explaining the normal function of CstF; 0.5 pt for explaining the normal function of polyA polymerase; 1 pt for explaining why the mutation you chose would be more likely to prevent proper termination, with reference to...

1. Why is iPS cell therapy using third-party donor cells more feasible than using cells donated from the patient being treated? O Treatment with iPS cells is much more cost prohibitive when iPS cells are donated by the patient being treated. O Donor iPS cells from the patient cannot be used because they contain the disease being treated. O Third-party donor cells are less likely to contain dangerous mutations that can lead to tumor formation. O Third-party donors are screened...
