E)channel proteins.

Question

Quizplus · Accepted Answer

Cyclins and cyclin-dependent kinases are proteins that participate in the regulation of the cell cycle by acting as key components of the checkpoints that monitor cell progression. They ensure that the cell has completed all necessary processes before advancing to the next stage of the cell cycle. The other options (microtubules, asters, histones, and channel proteins) do not play a significant role in the functioning of the cell cycle checkpoints.
