What is the purpose of cell cycle checkpoints?
A
To coordinate a cell’s specialization for its role in particular tissues.
B
To prevent the cell from pausing the cell cycle when problems are detected.
C
To ensure that cells containing errors in their DNA do not undergo apoptosis.
D
To coordinate movement of vesicles through the cell.
E
To ensure that a cell only proceeds to the next phase in the cell cycle if it is ready.

Understand that the cell cycle is a series of phases that a cell goes through to grow and divide, including phases like G1, S, G2, and M.
Recognize that cell cycle checkpoints are control mechanisms that monitor and verify whether the processes at each phase of the cell cycle have been accurately completed before the cell proceeds to the next phase.
Know that the main purpose of these checkpoints is to prevent the cell from moving forward if there are errors, such as DNA damage or incomplete replication, ensuring the integrity of the cell's genetic material.
Realize that by halting the cycle when problems are detected, checkpoints allow time for repair or, if the damage is irreparable, trigger programmed cell death (apoptosis) to prevent the propagation of faulty cells.
Conclude that the checkpoints ensure the cell only proceeds to the next phase when it is fully ready, maintaining proper cell function and preventing potential issues like cancer.
