Answer 2

Packaging Of DNA Helix

✏ In prokaryotes, there is no well defined nucleus.

✏ In eukaryotes the organisation of DNA is much more complex.

✏ There is a set of positively charged basic proteins called histones.

✏ A protein acquires charge due to the abundance of amino acid residues with charged side chains.

✏ There are five types of histone proteins H1, H2A, H2B, H3 and H4.

✏ Four of them ( H2A, H2B, H3 and H4 ) occur in pairs to produce histone octomer called nu – body or Core.

✏ Their charged ends are towards outside.

✏ DNA connecting the two adjacent nucleosome is called interbead or linker DNA and bears H1.
