Answer 1

Ans: Euchromatic regions.

Euchromatic regions are defined as the lightly packed regions of chromatin that possess the genes which often participate in the process of transcription and consist of about 90-92% of the entire human genome. They appear as light color bands upon staining in G banding whereas heterochromatin appears darkly stained. Telomere is located at the end of chromosome that contains repetitive nucleotide sequences and centromere is located at the center of chromosome which links the sister chromatids, thus they are not applicable.
