Question

Which statement is correct
1) Nucleosome consists of H2A, H2B, H3 and H4 (and H1 is not the part of nucleosome) and Euchromatin
has/is less number of protein, stains light and transcriptionally inactive.
2) Nucleosome has H1, H2A, H2B and H3 (H4 is not the part of nucleosome) and Heterochromatin is
densely packed, stains light and transcriptionally inactive.
3) Nucleosome has H2A, H2B, H3 and H4 (H1 is not the part of nucleosome) and Euchromatin is densely
packed, stains dark and Transcriptionally inactive.
4) Nucleosome has H2A, H2B, H3 and H4 (H1 is not the part of nucleosome) and Heterochromatin is
densely packed, stains dark and transcriptionally inactive.

Answer 1

Answer:

4

Explanation:

h1 is located outside the nucleosome

euchromatin is transcriptionally active lightly stained part of chromatin
