$DNA$ of heterochromatin

Vedclass · Answer

(B) The correct answer is $(b)$. Heterochromatin is a tightly packed form of $DNA$ that is genetically inactive or inert. Because it is so densely coiled,the transcriptional machinery cannot access the $DNA$ sequences,meaning it does not undergo transcription to produce messenger $RNA$ $(mRNA)$ for protein synthesis. In contrast,euchromatin is loosely packed and is transcriptionally active.

Which of the following is genetically inert and does not transcribe messenger $RNA$ for protein synthesis?
