Difference Between Euchromatin And Heterochromatin

the Heterochromatin always remains highly condense during the interphase. it is also not actively transcribed. on the other hand, Euchromatin is considered less condensed during the interphase and is actively transcribed. it also becomes highly condensed during mitosis. the basic difference between Euchromatin And Heterochromatin is that Heterochromatin appeared as a tight-packed form of DNA, highly dense, and exhibit heteropycnosis in which replication happens lately. while Euchromatin appeared as a loosely packed form of DNA, do not exhibit heteropycnosis, low dense and present and prokaryotes and eukaryotes.

Difference Between Euchromatin And Heterochromatin in Tabular Form

Euchromatin  Heterochromatin
A loosely packed form of DNA A tightly packed form of DNA
Does not exhibit Heteropycnosis Exhibits Heteropycnosis
Low DNA density High DNA Density
Found in Prokaryotes as well as eukaryotes Found in Eukaryotes only
in Active State Present in an Inactive state
Early replicative Late replicative
Regions are not sticky Sticky regions
The inner body of the nucleus is present presence of The periphery of the nucleus
No or little transcriptional activity Participate in the transcriptional activity
Euchromatin is lightly stained under nuclear stains. Heterochromatin is darkly stained under nuclear stains.
All the chromosomes in the genome except the heterochromatin are examples of euchromatin. Telomeres and centromeres, Barr bodies, one of the X chromosomes, genes 1, 9, and 16 of humans are some examples of heterochromatin.
