Acell has damaged dna, which checkpoint is responsible for checking this?

Question

Cell cycle checkpoints are essential control mechanisms that ensure proper cell division. In the cell cycle, there are two key checkpoints: the G1 checkpoint and the G2 checkpoint. The G1 checkpoint occurs just before the S phase, while the G2 checkpoint takes place right before the M phase. The G2 checkpoint specifically functions as a DNA damage checkpoint; if DNA is found to be damaged, the cell cycle is delayed to allow for repair before mitosis (M phase) can proceed. Therefore, in the case of a cell with damaged DNA, the G2 checkpoint is responsible for assessing and responding to this damage.

The answer is B: G2 checkpoint.Cell cycle checkpoints are control mechanisms necessary for proper cell division. In the cell cycle, there are two checkpoints: the G1 checkpoint and the G2 checkpoint. The G1 checkpoint is right before the S phase, and G2 checkpoint is right before the M phase.The G2 checkpoint is a DNA damage checkpoint and if DNA is damaged, entering the cell cycle is delayed before mitosis (M phase).

B) The cell can enter the G0 (resting stage) until conditions can improve.Explanation: The problem needs to be fixed before we can continue to other phases which is why the cell has check points.

BExplanation:it will go into G0 until conditions improve. If they dont it will go through apoptosis

The correct answer is option A. "M checkpoint".Explanation:The M checkpoint is one of the controls of the cell cycle, and the one that determines if cell division has occurred properly. During the M checkpoint the cell checks if the sister chromatids are properly attached to the spindle microtubes at the centromere. This characteristic is an indicative that cell division took place without any major errors and that the cell cycle can continue.
