Distinguish between heterochromatin and euchromatin. Which of the two is transcriptionally active?

$\text{Tabular form:}$

Criteria	Euchromatin	Heterochromatin
Definition	Euchromatin is the region of DNA that is loosely packed	Heterochromatin is the region of DNA that is tightly packed
Type of packaging	Euchromatin is loosely packaged as it contains histone proteins wrapped around by 147 base pairs of DNA around them.	Heterochromatin is tightly packaged as it contains 200 base pairs of DNA around them.
Staining	Euchromatin is lightly stained.	Heterochromatin is darkly stained.
Transcription	Euchromatin is a transcriptionally active region of DNA.	Heterochromatin is a transcriptionally inactive region of DNA.
