### Question 88

**How do DNA and RNA differ?**

- ○ DNA is double stranded while RNA is single stranded.
- ○ all statements are differences between DNA and RNA.
- ○ Thymine is present in DNA but not in RNA.
- ○ DNA has the sugar deoxyribose and Ribose is the sugar in RNA.

*Explanation:*

This question is designed to assess knowledge about the structural and functional differences between DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). 

1. **Double-Stranded vs. Single-Stranded:**
   - DNA is typically double stranded, forming a double helix structure, while RNA is usually single stranded.

2. **Base Composition:**
   - In DNA, the base thymine (T) pairs with adenine (A). In RNA, uracil (U) takes the place of thymine.

3. **Sugar Component:**
   - DNA contains the sugar deoxyribose, whereas RNA contains the sugar ribose.

4. **Correct Answer:**
   - The correct answer is likely, "all statements are differences between DNA and RNA," since each of the individual statements is true and differentiates DNA from RNA.
