The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Nucleosides and Nucleotides:** - A nucleoside consists of two components: a nitrogenous base and a pentose sugar (which can be ribose or deoxyribose). - A nucleotide, on the other hand, is composed of three components: a nitrogenous base, a pentose sugar, and a phosphate group. 2. **Identifying the Key Difference:** - The primary difference between a nucleoside and a nucleotide is the presence of the phosphate group. - In a nucleoside, only the nitrogenous base and the pentose sugar are present, while in a nucleotide, the phosphate group is also included. 3. **Conclusion:** - Therefore, a nucleoside differs from a nucleotide in that it lacks the phosphate group. **Final Answer:** A nucleoside differs from a nucleotide because it lacks the phosphate group. ---
