What happens during the cell cycle so that the abnormal cells are not produced?

During the cell cycle, several mechanisms ensure that abnormal cells are not produced. Key processes include DNA replication and repair, where any errors are corrected before cell division. Additionally, checkpoints throughout the cycle monitor for DNA damage or other abnormalities, preventing cells with issues from progressing to the next phase. If severe damage is detected, the cell may undergo apoptosis, or programmed cell death, to eliminate potential threats to the organism.
