When bound to its specific CDK, one cyclin is apparently responsible for assembling metaphase chromosomes. The cyclin responsible for this assembly is likely Cyclin E, which peaks during the G1 phase of the cell cycle.

Question

Quizplus · Accepted Answer

Cyclin responsible for metaphase chromosome assembly is not Cyclin E, which indeed peaks during the G1 phase and is primarily involved in the G1/S transition of the cell cycle. The cyclin involved in metaphase chromosome assembly is more closely associated with the activities of the M phase, such as Cyclin B, which partners with CDK1 to initiate mitosis.
