Chromatin material which remains condensed during interphase is called

Options

A. Heterochromatin
B. Euchromatin
C. Chormonemata
D. Megachromatin

Answer

To answer the question "Chromatin material which remains condensed during interphase is called," we can follow these steps:

1. **Understand Chromatin**: Chromatin is a complex of DNA and proteins found in eukaryotic cells. It exists in two forms: euchromatin and heterochromatin.

2. **Identify the Types of Chromatin**:
- **Euchromatin**: This form of chromatin is less condensed and is actively involved in transcription. It is typically found in regions of the genome that are being expressed.
- **Heterochromatin**: This form is more condensed and is generally not actively transcribed. It is found in regions of the genome that are not expressed or are silenced.

3. **Focus on the Question**: The question specifically asks about chromatin that remains condensed during interphase. This indicates that we are looking for the form of chromatin that does not unwind for transcription during this phase of the cell cycle.

4. **Select the Correct Answer**: Since heterochromatin remains condensed during interphase and is known for its dense structure, the correct answer to the question is:
- **Heterochromatin (Option a)**.

5. **Conclusion**: Therefore, the chromatin material that remains condensed during interphase is called heterochromatin.
