Problem:
Question 1: How does the cell repair mutations in DNA during replication? How are DNA mutations repaired at other times in the cell cycle?
Question 2: Predict the effects of a reduced rate of cardiac muscle contraction on the duration of the isovolumic contraction phase of the cardiac cycle. What would be the likely effects of hypertension on the duration of of the isovolumic phase?
Could someone help to explain the answer of these questions.
