Difference Between Euchromatin And Heterochromatin

Heterochromatin is defined as the area of the chromosome which is darkly stained with a DNA specific stain and is in comparatively condensed form. Euchromatin is defined as the area of the chromosome which is rich in gene concentration and actively participates in the transcription process. It is found in the nucleus of eukaryotes as well as prokaryotes. To help you understand how they differ from each other, we have given the difference between Euchromatin and Heterochromatin.

Sticky/Non-sticky Regions are not sticky Sticky regions
Presence Inner body of the nucleus The periphery of the nucleus
Activity No or little transcriptional activity Participate in the transcriptional activity
