Question

Quizplus · Accepted Answer

MPF (M-phase promoting factor) is composed of cyclin and a cyclin-dependent kinase (CDK). The levels of cyclin and CDK activity fluctuate through the cell cycle, peaking during M-phase (mitosis). The interaction of cyclin with CDK is necessary for the activation of MPF, which promotes entry into mitosis.
