The vitamin that involves in metabolism of nucleic acids is

Options

A. Folic acid
B. Biotin
C. Riboflavin
D. Cynacobalamine

Answer

To answer the question regarding which vitamin is involved in the metabolism of nucleic acids, we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Understanding Nucleic Acids**: Nucleic acids, which include DNA and RNA, are essential for genetic information storage and transfer. Their metabolism involves various biochemical processes.

2. **Identifying Key Vitamins**: The metabolism of nucleic acids requires specific vitamins that act as coenzymes or cofactors in these biochemical reactions.

3. **Folic Acid**: One of the most important vitamins for nucleic acid metabolism is Folic Acid (Vitamin B9). It plays a crucial role in the synthesis of nucleotides, which are the building blocks of nucleic acids.

4. **Vitamin B12**: Another vital vitamin involved in nucleic acid metabolism is Vitamin B12 (Cobalamin). It works closely with Folic Acid in the synthesis of nucleotides and is essential for DNA synthesis.

5. **Other Vitamins**: While Folic Acid and Vitamin B12 are the most significant, other vitamins like Riboflavin (Vitamin B2), Biotin (Vitamin B7), Niacin (Vitamin B3), and Thiamine (Vitamin B1) also contribute to the overall metabolism of nucleic acids, but they are not as critical as the first two.

6. **Conclusion**: Therefore, the vitamins most involved in the metabolism of nucleic acids are Folic Acid and Vitamin B12.

### Final Answer:
The vitamins that are involved in the metabolism of nucleic acids are **Folic Acid (Vitamin B9)** and **Vitamin B12 (Cobalamin)**.
