Question

Which statement does not describe cell cycle checkpoints?

A. Normal checkpoints assess damage to DNA.
B. Faulty checkpoints may lead to abnormal cell growth.
C. Cell checkpoints can fail in mitosis and meiosis.
D. Cells that bypass the G2 checkpoint move to the synthesis stage.

Please select the option that does not accurately describe cell cycle checkpoints.

Answer 1

The incorrect statement about cell cycle checkpoints is that d) cells bypassing the G2 checkpoint move to the synthesis stage; they actually move to mitosis.

Step-by-step explanation:

The statement that does not accurately describe cell cycle checkpoints is: d) Cells that bypass the G2 checkpoint move to the synthesis stage. This statement is incorrect because cells that pass the G2 checkpoint do not move back to the synthesis (S) phase; instead, they proceed to mitosis. The primary role of the G2 checkpoint is to ensure that DNA replication is complete and the DNA is not damaged before the cell enters mitosis. Therefore, a cell passing the G2 checkpoint would logically move into mitosis (the M phase), not the synthesis phase.
