A nucleoside differs form a nucleotide . It lacks the

Options

A. Glycosidic bonds
B. Phosphodiester bonds
C. Peptide bonds
D. Hydrogen bonds

Explanation

### Step-by-Step Solution:

1. **Understanding Nucleosides and Nucleotides**:
- A nucleoside consists of a sugar (either ribose or deoxyribose) and a nitrogenous base.
- A nucleotide, on the other hand, includes a sugar, a nitrogenous base, and one or more phosphate groups.

2. **Identifying the Key Differences**:
- The main difference between a nucleoside and a nucleotide is the presence of phosphate groups in nucleotides. Nucleosides do not have these phosphate groups.

3. **Types of Bonds**:
- Nucleosides are connected through glycosidic bonds (between the sugar and the nitrogenous base).
- Nucleotides are connected through phosphodiester bonds (between the sugar and the phosphate group).

4. **Analyzing the Options**:
- The question asks what a nucleoside lacks compared to a nucleotide.
- Since nucleosides do not have phosphate groups, they also do not have phosphodiester bonds.

5. **Conclusion**:
- Therefore, the correct answer is that a nucleoside lacks phosphodiester bonds.

### Final Answer:
A nucleoside differs from a nucleotide in that it lacks **phosphodiester bonds**.
