Go through the following statements: (i) a typical nucleosome contains 400 bp of DNA helix. (ii) The positively charged DNA is wrapped around the negatively charged histoned octamer to form a structure called nucleosome. (iii) Histones are rich in the basic amino acid residues asparagine ad valine (iv) The packaging of chromatin at higher level requires additional set of proteins that collectively are referred to as nonhistone chromosomal proteins. Find out the wrong statements:-
