Question

What would happen if there was a loss of function in the CDKs?

A) Increased cell cycle progression
B) Decreased cell cycle progression
C) Inhibited apoptosis
D) Enhanced DNA repair

Answer 1

Loss of function in CDKs would result in decreased cell cycle progression. The correct answer is B).

Step-by-step explanation:

If there was a loss of function in the CDKs (cyclin-dependent kinases), it would result in decreased cell cycle progression. CDKs play a crucial role in regulating the cell cycle by phosphorylating target proteins and allowing cell cycle progression. Loss of CDK function would disrupt this process, leading to a decrease in cell cycle progression.

For example, CDKs are involved in the G1 checkpoint, where they inhibit the transition from G1 to S phase. Loss of CDK function would compromise this checkpoint, and cells would proceed directly from G1 to S phase, bypassing the normal regulatory mechanisms.

Therefore, the correct answer is B) Decreased cell cycle progression.
