Question

Genetically active and rich in loosely packed DNA is?

• A. Heterochromatin
• B. Euchromatin
• C. Both $1$ & $2$
• D. Centromere

Answer 1

The correct option is B Euchromatin

Euchromatin is a form of chromatin that is lightly packed as opposed to heterochromatin, which is densely packed. The presence of euchromatin usually reflects that cells are transcriptionally active, i.e. they are actively transcribing DNA to mRNA.

Hence, the correct answer is (B)
