Question

what is the purpose of cell cycle checkpoints?
○ to coordinate cell specialization for its role in particular tissues
○ to coordinate movement through the cell cycle among multiple cells
○ to ensure that cells containing errors in their dna do not undergo apoptosis
○ to prevent the cell from pausing the cell cycle when problems are detected
○ to ensure that cell cycle phases proceed only when the cell is ready

Explanation:

Cell cycle checkpoints monitor the cell's readiness for each phase. They halt the cycle if issues like DNA damage are detected, allowing time for repair. Once resolved, the cycle resumes. This ensures proper cell division and function. Other options are incorrect: cell specialization (differentiation) isn't their role; they act within a single cell, not multiple; they trigger apoptosis if DNA errors are unrepairable (opposite of one option); and they cause pauses (contrary to another option).

Answer:

to ensure that cell cycle phases proceed only when the cell is ready
