Monosaccharide found in nucleolus is

Options

A. pentose
B. tetrose
C. erythrose
D. hexose

Answer

To answer the question "Monosaccharide found in nucleolus is," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Monosaccharides**:
- Monosaccharides are the simplest form of carbohydrates, consisting of a single sugar unit. They are the building blocks of more complex carbohydrates.

2. **Identifying the Options**:
- The options given are:
- A) Pentose
- B) Tetrose
- C) Erythrose
- D) Hexose

3. **Analyzing the Options**:
- **Pentose**: This is a five-carbon sugar. Important examples include ribose and deoxyribose, which are crucial components of nucleic acids (RNA and DNA, respectively).
- **Tetrose**: This is a four-carbon sugar. It is not commonly found in nucleic acids.
- **Erythrose**: This is a specific type of tetrose and is not typically associated with nucleic acids.
- **Hexose**: This is a six-carbon sugar, such as glucose, which is not primarily found in nucleic acids.

4. **Conclusion**:
- The monosaccharides that are specifically found in the nucleolus, where nucleic acids are synthesized, are pentoses (ribose and deoxyribose). Thus, the correct answer is **A) Pentose**.

### Final Answer:
The monosaccharide found in the nucleolus is **Pentose**.
