For cells to divide more rapidly,increased production would likely be required of each of the following proteins EXCEPT
A)p53.
B)cyclins.
C)activated MPF.
D)PDGF.

Question

Quizplus · Accepted Answer

p53 is a tumor suppressor protein that is responsible for inhibiting cell division in response to DNA damage. Its increased production would actually slow down the rate of cell division, not increase it. On the other hand, cyclins, activated MPF, and PDGF are all proteins that play important roles in promoting cell division and would need to be produced in higher amounts for cells to divide more rapidly.
