Transition from G2 to M phase of the cell cycle is controlled by which of the following cyclins?: (A) Cyclin D, (B) Cyclin A, (C) Cyclin E, (D) Cyclin B
Answer is D. Examples of cyclin/CDK complexes controlling the cell cycle. Cyclin B/CDK1 Regulates the transition from G2 to M phase Cyclin D-Cdk4/6 Regulates the transition from G1-S Cyclin D/CDK4, Cyclin D/CDK6, Cyclin E/CDK2, Cyclin A/CDK2 and cyclin B/ CDK1 Active in S phase
