Which is the transcriptionally inactive chromatin ?

A

Euchromatin

B

Heterochromatin

C

Loosely packed chromatin

D

Both B and C

Text Solution

Verified by Experts

The correct Answer is:
B
`**" "`In a typical nucleus, some region of chromatin are loosely packed (and strains light) and are referred to as euchromatin.
`**" "` The chromatin that is more densely packed and stains dark are called as Heterochromatin.
`**" "`Euchromatin is said to be transcriptionally active chromatin, whereas heterochromatin is inactive.
