(i) Histone proteins help in packaging of DNA. These are organised to form a unit of eight molecules called as histone octamer. The negatively charged DNA is wrapped around the positively charged histone octamer to from a structure called nucleosome. (ii) Non-histone chromosomal proteins helps in packaging of chromatin at higher levels.
