What phase do cells spend most of their time in?

• Interphase

• G2 phase

• M phase

• S phase

What happens if a cell does not meet the requirements of a checkpoint and cannot fix the issue?

• It continues to divide.

• It stops growing.

• It moves to the next phase.

• It undergoes apoptosis.

What is the role of cyclin and Cdk in the cell cycle?

• They stop the cell cycle.
