Perinuclear space is about -

Options

A. 10 - 50 nm
B. 1 - 5 nm
C. 100- 500 nm
D. 10 - 50m

Answer

To answer the question regarding the width of the perinuclear space, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Perinuclear Space**: The perinuclear space is the area between the inner and outer membranes of the nuclear envelope. It separates the nucleus from the cytoplasm.

2. **Identifying the Width**: The width of the perinuclear space is a specific measurement that is typically defined in nanometers (nm).

3. **Analyzing the Options**: The options given are:
- 10 to 15 nanometers
- 1 to 5 nanometers
- 100 to 500 nanometers
- 10 to 50 meters

4. **Evaluating Each Option**:
- **10 to 15 nanometers**: This is too narrow compared to the typical measurement.
- **1 to 5 nanometers**: This is also too narrow.
- **100 to 500 nanometers**: This is too wide for the perinuclear space.
- **10 to 50 meters**: This is an incorrect unit of measurement for cellular structures.

5. **Correct Answer**: Based on the understanding of the perinuclear space, the correct width is between **10 to 50 nanometers**.

### Final Answer:
The perinuclear space is about **10 to 50 nanometers** wide.
