Question

Heterochromatin is transcriptionally inactive when compared to euchromatin Give reason.​

Answer 1

Answer:

Heterochromatin is densely packed and inaccessible to transcription factors so it is rendered transcriptionally silent (Richards and Elgin 2002). Euchromatin, on the other hand, is less condensed, more accessible, and therefore transcriptionally active (Hennig 1999).
