A) It is highly expanded in interphase
B) It stains densely with basic dyes
C) It is highly condensed in interphase
D) It stains densely with acidic dyes
Correct Answer: B
Solution :
Heterochromatin is a tightly packed from of DNA, that stains intensely, indicating tighter packing. Both centromeres and telomeres are heteroch, romatic. Heterochromatic telomeres remains condensed during interphase where as euchromatin decondenses during interphase. DNA is acidic in nature and therefore stains basic dyes. Loosely coiled chromatin (euchromatin) stainslightly with basic dyes whereas tightly coiled DNA (heterochromatin) stains darkly with basic dyes.
