Q.
Histone proteins are
Molecular Basis of Inheritance
Solution:
In eukaryotes, $DNA$ organisation is complex. There is a set of positively charged, basic proteins called histones. Histones are rich in the basic amino acid residues lysine and arginine. There are five types of histone proteins $- H_{1}, H_{2}A, H_{2}B, H_{3}$ and $H_{4}$. Four of them ($H_{2}A, H_{2}B, H_{3}$ and $H_{4}$) produce histone octamer called nu body or core of nudeosome. The negatively charged $DNA$ is wrapped around the positively charged histone octamer to form nudeosome. $DNA$ connecting two adjacent nudeosomes is called linker $DNA$ which bears $H_{1}$ histone proteins.
