The cell cycle is regulated at the molecular level by a set of proteins known as
A)ATPases.

C)cohesins.
D)cyclins.

Question

Quizplus · Accepted Answer

The cell cycle is regulated by a group of proteins called cyclins. Cyclins regulate the progression of the cell cycle by activating cyclin-dependent kinases (CDKs). The levels of cyclins rise and fall throughout the cell cycle, activating and inactivating CDKs in a precise manner. This ensures that the cell progresses through each phase of the cell cycle in the correct order and at the proper speed.
