Difference between Euchromatin and Heterochromatin | Chromatin

The upcoming discussion will update you about the differences between Euchromatin and Heterochromatin.

Difference # Euchromatin:

1. It is narrower, 10-30 nm in diameter.

2. Euchromatin is lightly stained.

3. It is somewhat diffused.

4. Euchromatin is fibrous.

5. It forms the bulk of chromatin.

6. It contains active genes.

7. Euchromatin takes part in transcription.

8. Euchromatin is affected by a number of factors like pH, temperature and hormones.

9. Crossing over is quite common.

10. It replicates early.

11. Nucleosome strand has minimum coiling.

Difference # Heterochromatin:

1. Heterochromatin is thicker, 100 nm in diameter.

2. It is darkly stained.

3. Heterochromatin is condensed.

4. Heterochromatin is granular.

5. It is present at certain places in the chromatin.

6. Heterochromatin does not possess active genes.

7. Transcription is absent in heterochromatin.

8. Heterochromatin is not influenced by these factors.

9. Heterochromatin inhibits crossing over.

10. It replicates late in the S-phase.

11. Nucleosome strand has solenoid coiling.
