QuestionSBA
QuestionChoice
This is incorrect. The G2 checkpoint is located after the S phase of the cell cycle and not after the M phase therefore it cannot ensure that cytoplasmic division has occurred successfully.

e
To ensure that cytoplasmic division has occurred successfully
QuestionChoice
This is incorrect as it is describing the G1 checkpoint. The G1 checkpoint is known as the restriction point, if a cell does not pass this checkpoint it enters quiescence by switching to a non-dividing state known as G0.

d
To allow for the cell to exit the cell cycle and switch to a non-dividing state known as G0 if it does not pass the checkpoint
QuestionChoice
This is incorrect as it is describing the G1 checkpoint. The G1 checkpoint is known as the restriction point, if a cell passes this point it is usually able to continue with the cell cycle.

c
Ensures that the cell is large enough to divide and that enough nutrients are available to support the daughter cells
QuestionChoice
This is incorrect as it is describing the metaphase checkpoint. The metaphase checkpoint ensures that the cell is in the right condition to move on.

b
Ensures that all of the chromosomes are attached to the mitotic spindle by a kinetochore
QuestionChoice
The G2 checkpoint is located after the S phase. This is to ensure that replication has been completed successfully before the cell enters the G2 phase.

a
Ensures that DNA replication in the S phase has been completed successfully
