Final answer:
Vitamin C is recognized for its antioxidant qualities that help protect DNA from oxidative damage but does not directly repair DNA. Vitamins A, D, E, and K are fat-soluble and can be stored in the body, whereas Vitamin C, being water-soluble, is not stored and is expelled if taken in excess.
Step-by-step explanation:
Vitamin's Role in DNA Repair
Among the options provided, Vitamin C is acknowledged for its role as an antioxidant, which can protect the body from damage by free radicals, including damage to the DNA. While not repairing DNA directly, it helps by blocking damaging agents like oxidants. However, there isn't a vitamin listed that directly repairs DNA on its own. Vitamins like Vitamin A and Vitamin E also have antioxidant properties but are not directly responsible for DNA repair. Vitamin K is primarily essential for blood clotting, not DNA repair.
Vitamin C is also a water-soluble vitamin, meaning it dissolves in blood and is not stored in the body. Excess amounts are expelled through urine. On the other hand, Vitamins A, D, E, and K are fat-soluble, meaning they can be stored in body fat and potentially reach unhealthy levels if consumed in excess.
In terms of vitamins stored in the body, phosphorous is a mineral that is stored in the body, as well as Vitamin A and Vitamin K, which are both fat-soluble vitamins.
