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

Question

Quizplus · Accepted Answer

p53 is a tumor suppressor protein, and increased production of p53 would actually slow down cell division, as it functions to monitor and repair DNA damage before allowing cells to progress through the cell cycle. Increased production of activated MPF, cyclins, and PDGF would all contribute to increased cell division.
