DNA is different from RNA because DNA contains:

Options

A. ribose sugar and thymine
B. ribose sugar and uracil
C. deoxyribose sugar and thymine
D. deoxyribose sugar and uracil

Explanation

To solve the question, "DNA is different from RNA because DNA contains:", we need to analyze the components of DNA and RNA.

### Step-by-Step Solution:

1. **Identify the Full Forms**:
- DNA stands for Deoxyribonucleic Acid.
- RNA stands for Ribonucleic Acid.

2. **Examine the Sugar Component**:
- DNA contains deoxyribose sugar.
- RNA contains ribose sugar.
- This is a key difference between the two nucleic acids.

3. **Identify the Nitrogenous Bases**:
- DNA contains the nitrogenous bases: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
- RNA contains the nitrogenous bases: Adenine (A), Uracil (U), Cytosine (C), and Guanine (G).
- Notably, DNA has Thymine (T), while RNA has Uracil (U).

4. **Conclusion**:
- The main difference between DNA and RNA is that DNA contains deoxyribose sugar and the nitrogenous base Thymine, whereas RNA contains ribose sugar and Uracil.

### Final Answer:
DNA is different from RNA because DNA contains deoxyribose sugar and Thymine.
