If a given protein's level peaks early in G₁, but is absent before the G₂ transition, what can be inferred about its possible role in regulating the cell cycle?

Question

Quizplus · Accepted Answer

The protein's peak in early G1 and absence before G2 suggests it may be involved in the regulation of the G1 phase, where Cdk2 is active. Therefore, it is likely to activate Cdk2, which is crucial for the progression from G1 to S phase.
