Final answer:
Cisplatin, carboplatin, and oxaliplatin are platinum-based chemotherapy drugs that inhibit cell division by forming covalent bonds with DNA, preventing DNA strands from separating. They replace chloride ions with water molecules and react with DNA, preventing cell division and tumor growth.
Step-by-step explanation:
Cisplatin, carboplatin, and oxaliplatin are all platinum-based chemotherapy drugs that are used in the treatment of cancer. They work by forming covalent bonds with DNA, which prevents the DNA strands from separating and inhibits cell division. Specifically, cisplatin replaces chloride ions with water molecules, and the resulting species reacts with DNA to prevent cell division and tumor growth.
