Question

Select the statement which is not true regarding DNA packaging in eukaryotes.
[0.7 mark]

• A. DNA packaging is much more complex as compared to prokaryotes
• B. Histones are positively charged basic proteins
• C. Negatively charged DNA is wrapped around histone octamer
• D. Histones in nucleosome are rich in leucine and glycine

Answer 1

The correct option is D Histones in nucleosome are rich in leucine and glycine

In eukaryotes, packaging of DNA is much more complex and is carried out by a set of positively charged basic proteins called histones. Histones are rich in the basic amino acids residues Iysines and arginines. The negatively charged DNA is wrapped around the positively charged histone octamer to form a structure called nucleosome.
