Biology

The correct answer is: D.The cell undergoes apoptosis or enters a repair mechanism.

During the S phase, if DNA damage occurs, the cell typically activates repair mechanisms to fix the damage. If the damage is severe and cannot be repaired, the cell may undergo apoptosis (programmed cell death) to prevent the propagation of damaged DNA. This ensures the integrity of the genetic material before the cell progresses to the M phase (mitosis).

A.The DNA replication process continues without interrupt...
