The carbohydrate present in DNA is

Options

A. L-glucose
B. D-ribose
C. 2-Deoxyribose
D. Fructose

Answer

**Step-by-Step Solution:**

1. **Identify the Full Form of DNA:**
- DNA stands for Deoxyribonucleic Acid. This name gives us a clue about the components of DNA.

2. **Focus on the Sugar Component:**
- The term "Deoxyribonucleic" indicates that there is a sugar present in DNA. Specifically, it refers to the sugar component of the nucleotides that make up the DNA structure.

3. **Determine the Type of Sugar:**
- The sugar in DNA is known as deoxyribose. To distinguish it from other sugars, we can compare it to ribose, which is found in RNA (Ribonucleic Acid).

4. **Compare Ribose and Deoxyribose:**
- Ribose has a hydroxyl group (-OH) attached to its second carbon atom. In contrast, deoxyribose lacks this hydroxyl group at the second carbon, having only a hydrogen atom instead. This absence of one oxygen atom is what gives deoxyribose its name (2-deoxyribose).

5. **Conclusion:**
- Therefore, the carbohydrate present in DNA is 2-deoxyribose.

**Final Answer:**
The carbohydrate present in DNA is 2-deoxyribose.
