Answer 1

Answer:

A. Euchromatin, Heterochromatin

Inside the typical structure of a nucleus, the part of the chromatin which is considerably loose and stains light is said to be the Euchromatins. Likewise, the part of the chromatin which is considerably dense and stains dark is said to be the Heterochromatins. The part which is loose is said to be transcriptionally active, and the dense part is said to be transcriptionally inactive.
