A condensation product of nitrogen base and pentose sugar is

Options

A. nucleotide
B. nucleic acid
C. nucleoside
D. None of these

Answer

To solve the question "A condensation product of nitrogen base and pentose sugar is," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Components**:
- Identify the two components mentioned in the question: nitrogen base and pentose sugar.
- Nitrogen bases include adenine, thymine, cytosine, guanine, and uracil.
- Pentose sugars include ribose (found in RNA) and deoxyribose (found in DNA).

2. **Define the Process**:
- The term "condensation" refers to a chemical reaction where two molecules combine to form a larger molecule, with the loss of a small molecule, often water.
- In this case, the nitrogen base and pentose sugar will undergo a condensation reaction.

3. **Identify the Product**:
- When a nitrogen base and a pentose sugar combine, they form a nucleoside.
- A nucleoside consists of a nitrogen base linked to a pentose sugar via a glycosidic bond.

4. **Conclusion**:
- Therefore, the condensation product of a nitrogen base and a pentose sugar is a nucleoside.

### Final Answer:
The answer is **nucleoside**.
