Question

(expanded) back into chromatin? a) chromatin remodeling complexes compact or relax naked DNA molecules b) naked DNA associates with histones (H2A, H2B, H3 and H4) to create highly c) naked DNA associates with histones forming nucleosomes (chromatin) and chemical compacted DNA structures (heterochromatin). modifications at histone tail domains (acetylation, methylation or phosphorylation) determine if chromatin remodeling complexes promote compaction (heterochromatin) or relaxation (chromatin) of DNA protein complexes. d) histone H1 determines if a DNA region is to be compacted or retain its relaxed state

Explanation / Answer

Option C.

Naked DNA associates with histone forming Nucleosomes (chromatin) and chemical modification at histone tail domain namely acetylation, methylation, or phosphorylation determine if chromatin remodeling complexes promote compaction (heterochromatin) or relaxation (chromatin) of DNA protein complexes.

H1, H2A, H2B, H3, H4 are the type of histones which are associated with DNA molecule.
