Answer 2

Double Helix Of DNA

• In prokaryotes, there is no well defined nucleus.

• DNA being negatively charged is held with some proteins (polyamines) that have negative charges in a region are termed as nucleiod.

• 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 aminoacid residues with charged side chains.

• The histones proteins are rich in amino acid residues lysines and arginines.

• Both the amino acid residues carry positive charges in their side chains.
