Levels of Cdk Activity Change During the Cell Cycle, in Part

Question

Levels of Cdk activity change during the cell cycle, in part because
A)the Cdks phosphorylate each other.
B)the Cdks activate the cyclins.
C)Cdk degradation precedes entry into the next phase of the cell cycle.
D)cyclin activity change during the cycle.

Accepted Answer

Cyclin-dependent kinases (Cdks) are regulated by the binding of cyclins, whose levels fluctuate throughout the cell cycle. This fluctuation in cyclin levels causes changes in Cdk activity, enabling the cell cycle to progress through its various phases.
