Learn about the difference between Euchromatin and Heterochromatin.
Difference # Euchromatin:
1. The chromatin fibres in this region are loosely coiled as compared with hetero chromatic regions
2. Euchromatin is deeply stained in divisional cycle but less stained in interphase.
3. The region is genetically active and contains unique DNA.
4. Euchromatic regions are able to synthesize mRNA in vitro.
5. Euchromatic regions are seen to their DNA earlier than heterochromatin. They replicate during ‘S’ phase.
6. Due to addition or loss of this region phenotype is affected.
7. This region is not sticky.
8. The crossover frequency is more in euchromatin.
9. Euchromatin does not show heteropycnosis.
10. Euchromatin is less affected than hetero chromatin by temperature, sex, age, etc.
Difference # Heterochromatin:
1. The chromatin fibres in this region are more tightly folded than euchromatic regions.
2. Heterochromatin is deeply stained in interphase but less stained in divisional cycle.
3. Heterochromatic regions are unable to synthesize mRNA in vitro.
4. Heterochromatic regions are unable to synthesize mRNA in vitro size mRNA in vitro.
5. Heterochromatic regions are seen to replicate during the onset of divisional cycle.
6. Addition or loss of this region does not affect phenotype.
7. This region is sticky.
8. Crossover frequency is less than euchromatin.
9. Heterochromatin shows heteropycnosis.
10. Heterochromatin is more affected than euchromatin by temperature, sex, age of parents, proximity to the centromere.
