Vedclass · Answer

(D) During cell division,chromatin undergoes progressive condensation to form compact chromosomes.Chromatin is broadly classified into two types: $Euchromatin$ (loosely packed,transcriptionally active) and $Heterochromatin$ (densely packed,transcriptionally inactive).As condensation increases,the distinction between these two regions becomes more pronounced because the chromatin fibers pack into highly ordered,dense structures,making the heterochromatic regions more distinct from the euchromatic regions.Therefore,the differentiation between heterochromatin and euchromatin increases.
