Question

Which of the following is not a checkpoint for cell cycle control in a eukaryotic cell?

1) G1/S checkpoint
2) G2/M checkpoint
3) Metaphase checkpoint
4) Anaphase checkpoint

Answer 1

The metaphase checkpoint is not a checkpoint for cell cycle control in a eukaryotic cell

Step-by-step explanation:

The correct answer is 3) Metaphase checkpoint.

There are three major checkpoints in the cell cycle of a eukaryotic cell which are the G1/S checkpoint, G2/M checkpoint, and metaphase checkpoint. The G1/S checkpoint checks if the cell is ready to enter the synthesis phase, the G2/M checkpoint ensures that the DNA is properly replicated, and the metaphase checkpoint checks if all the chromosomes are properly aligned before cell division.
