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 couldn’t 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:

The G2 checkpoint verifies DNA integrity post-replication. If it fails with damaged DNA, the cell proceeds to divide, passing on damaged DNA. Uncontrolled division of damaged cells is the key outcome here, as the checkpoint would normally halt division to repair damage or trigger cell death.

Answer:

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