Question

Distinguish between heterochromatin and euchromatin with reference to staining property and activity.

Hint:

Euchromatin is associated with active gene expression, while heterochromatin is associated with inactive genes.

Answer 1

Step 1: Understanding Heterochromatin and Euchromatin.
Heterochromatin and euchromatin are two types of chromatin found in the nucleus.
- Heterochromatin: - It is densely packed and stains darker. - It is transcriptionally inactive and contains genes that are not being actively transcribed.
- Euchromatin: - It is loosely packed and stains lighter. - It is transcriptionally active and contains genes that are being transcribed.
Step 2: Conclusion.
Heterochromatin is dense and inactive, while euchromatin is less dense and active in gene expression.
