Question

select the correct answer.
a model cell with damaged dna was created to explain the importance of checkpoints in a cell cycle. the g2 checkpoint accidentally failed to work during experimentation. what do you think is the likely consequence of this failure?
a. the cell divided and created two cells with repaired dna
b. the cell couldnt divide, and cell division stopped.
c. the cell died before it could complete division.
d. the cell divided and created two nonidentical cells.
e. the cell continued to divide uncontrollably to create more damaged cells.

Explanation:

Cell cycle checkpoints, like the G2 checkpoint, ensure DNA is undamaged before cell division. If a checkpoint fails (here G2), damaged DNA can't be properly repaired. Without the checkpoint halting the process, the cell would keep dividing uncontrollably. This is a key concept in cell biology related to cancer (uncontrolled cell growth) as damaged DNA accumulation can lead to such scenarios. Options A - D don't align with the consequence of a failed checkpoint (which is about loss of control in division, not normal division outcomes like non - identical cells, cell death before division, or stopping division).

Answer:

E. The cell continued to divide uncontrollably to create more damaged cells.
