Euchromatin vs. Heterochromatin: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Euchromatin is loosely packed, transcriptionally active DNA, while Heterochromatin is densely packed, transcriptionally inactive DNA.
Key Differences
Euchromatin is characterized by a loosely packed chromatin structure, allowing easier access for transcription factors, contrasting with Heterochromatin, which has a tightly packed structure, restricting gene expression.

In terms of genetic activity, Euchromatin is rich in gene concentration and actively involved in transcription, whereas Heterochromatin is mostly transcriptionally inactive, containing few genes.

Euchromatin is found predominantly in regions of the genome where active gene expression occurs, while Heterochromatin is primarily located at the centromeres and telomeres, contributing to chromosome stability.
