Imagine that there is a mutation in the Cdk gene such that its gene product is nonfunctional.What effect will this mutation have on a mature red blood cell?
A) The cyclin bound to this Cdk will not be phosphorylated.
B) There will be no effect, because mature red blood cells do not enter the cell cycle.
C) The cell will not be able to replicate its DNA.
D) The cell will not be able to enter G1.

Mature red blood cells lose their nucleus and other organelles during development, and as a result, they do not have the ability to enter the cell cycle or divide. Therefore, a mutation in the Cdk gene that affects cell cycle regulation would have no effect on a mature red blood cell.
