Question

Chromatins are stained by
A. Acidic dye B. Basic dye
C. Crystal violet D. More than one​

Answer 1

Answer:

Mixtures of polychrome methylene blue-eosin Y (i.e., Giemsa stain) are widely used in biological staining. They induce a striking purple coloration of chromatin DNA (the Romanowsky-Giemsa effect), which contrasts with the blue-stained RNA-containing cytoplasm and nucleoli. After specific prestaining treatments that induce chromatin disorganization (giving banded or harlequin chromosomes), Giemsa staining produces a differential coloration, with C- and G-bands appearing in purple whereas remaining chromosome regions are blue. Unsubstituted (TT) and bromo-substituted (BT) DNAs also appear purple and blue,

acidic dye
