The correct answer is:
A B C
H1 histone Positively charged histone octamer Negatively charged DNA
Histones are rich in the basic amino acid residues lysine and arginine and hence are positively charged. Histones are organized to form a unit of eight molecules called histone octamer. The negatively charged DNA is wrapped around the positively charged histone octamer to form a structure called a nucleosome.
