Which cyclin/CDK complex is responsible for the transition to S-phase?
Understand the Problem
The question is asking which specific cyclin/CDK complex is responsible for the transition from G1 phase to S phase in the cell cycle.
Answer
CDK2-cyclin-A complex
The transition to the S-phase is regulated by the CDK2-cyclin-A complex.
Answer for screen readers
The transition to the S-phase is regulated by the CDK2-cyclin-A complex.
More Information
The CDK2-cyclin-A complex is crucial for initiating the S-phase of the cell cycle, which involves DNA replication. This complex ensures that replication is precisely controlled, preventing errors that can lead to cell malfunction.
Tips
A common mistake is confusing the role of different cyclin/CDK complexes in the cell cycle. Ensure you understand which complexes are responsible for each phase transition.
