Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : Euchromatin is less condensed DNA than heterochromatin DNA.
Reason (R) : Euchromatin is transcriptionally active DNA thus needs to provide the access to transcription machinery.
In light of the above statements, choose the correct answer from the options given below.
EXPLANATION
Transcription, RNA Processing, & Gene Regulat
- Assertion (A) is True: Euchromatin represents the lightly packed, decondensed form of chromatin (10 nm to 30 nm fiber), whereas heterochromatin remains densely compacted throughout the cell cycle.
- Reason (R) is True & Explains (A): Euchromatin is transcriptionally permissive and active; its uncoiled conformation is required to grant RNA polymerase II, general transcription factors, and chromatin-remodeling complexes physical access to promoter and enhancer elements.
- Conclusion: Both (A) and (R) are true and (R) is the correct explanation of (A).
Correct option: (1) Both (A) and (R) are true and (R) is the correct explanation of (A)
