Q89: Given below are two statements, one is labelled as Assertion... - Molecular Biology - Biochemistry- ICAR JRF/SRF 2024 | Agrigyan

• 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)
