DNA contains the sugar

Options

A. Deoxyribose
B. Ribose
C. D- fructose
D. D- glucose

Answer

To answer the question "DNA contains the sugar," we will analyze the options provided and identify the correct sugar present in DNA.

### Step-by-Step Solution:

1. **Understanding DNA**:
- DNA stands for Deoxyribonucleic Acid. It is a molecule that carries genetic information in living organisms.

2. **Identifying the Sugar in DNA**:
- The question asks about the type of sugar present in DNA. The sugar component of DNA is crucial for its structure.

3. **Analyzing the Options**:
- The options given are:
- a) Deoxyribose
- b) Ribose
- c) Defructose
- d) Deglucose

4. **Evaluating Each Option**:
- **Deoxyribose**: This is the sugar that is part of the DNA structure. It has one less oxygen atom compared to ribose.
- **Ribose**: This sugar is found in RNA (Ribonucleic Acid) and has an additional oxygen atom compared to deoxyribose.
- **Defructose**: This is not a standard sugar found in nucleic acids.
- **Deglucose**: This is also not a sugar that is part of DNA.

5. **Conclusion**:
- Since DNA contains deoxyribose as its sugar, the correct answer is **Deoxyribose**.

### Final Answer:
DNA contains the sugar **Deoxyribose**.
