How might dna damage go on to affect the rest of the cell cycle if apoptosis did not occur

The damage of DNA refers to the change in the chemical composition of DNA, like a break in a strand of DNA, a chemically modified base, or a base missing from the backbone. The damage of DNA can take place due to environmental factors or naturally.

Due to damage of DNA, that is, the cells have mutations so it might not undergo the process of cell cycle accurately or two cells may get formed and each may comprise the mutation.
