Question

Nucleosomes given beaded appearance to chromosomes. They help in packaging of DNA in chromosomes. A nucleosomes has (A) about two turn of DNA (B) 8 histone molecule (two molecule each of H3,H4,H2A .and H2B ) (C) 166 nitrogen base pairs (D) All of the above

Tardigrade Admin · Accepted Answer

Nucleosomes are found only in eukaryotic Chromosomes. Two nucleosomes are interconnected by linkes DNA, i.e., H1 -histone is not the part of nucleosome.

about two turn of DNA

8 histone molecule (two molecule each of $H_{3}, H_{4}, H_{2} A$ .and $H_{2} B$ )

166 nitrogen base pairs

All of the above

Nucleosomes are found only in eukaryotic Chromosomes. Two nucleosomes are interconnected by linkes DNA, i.e., $H_{1}$ -histone is not the part of nucleosome.
