Final answer:
Vitamins A, C, and E, along with beta-carotene, contribute to antioxidant systems to prevent DNA mutations. These vitamins function as antioxidants, neutralizing harmful free radicals that can damage DNA.
Step-by-step explanation:
Vitamins A, C, and E, as well as beta-carotene, are all vitamins that contribute to antioxidant systems to help prevent DNA mutations. These vitamins function as antioxidants, which means they can neutralize harmful free radicals that can cause DNA damage. For example, vitamin C and E react with free radicals to stop chain reactions and prevent oxidative damage to DNA, while vitamin A helps keep cells differentiated, slowing down the growth rate.
