E) inhibit DNA replication or DNA repair enzymes

Question

Quizplus · Accepted Answer

Cancer treatments often target rapidly dividing cells by using drugs or chemicals that inhibit processes crucial for cell division. Inhibiting DNA replication prevents the cell from making copies of its DNA, necessary for cell division. Inhibiting DNA repair enzymes prevents the cell from repairing any damage to its DNA, which can lead to cell death. Both strategies are used to target cancer cells, which divide more rapidly than most normal cells.
