If a dividing cell had no functional G1/S Cdk protein, the cell would not be able to ____.

B) transcribe the Cdk gene
C) enter S phase
D) translate cyclin mRNA
E) degrade cyclins

Question

Quizplus · Accepted Answer

The G1/S Cdk (cyclin-dependent kinase) is crucial for the transition from the G1 phase to the S phase in the cell cycle. Without functional G1/S Cdk, the cell cannot progress past the G1 checkpoint to enter the S phase, where DNA replication occurs.
