Question

Give reason: Histones are positively charged

Answer 1

Histones are a family of basic proteins that associate with DNA in the nucleus and help condense it into chromatin, they are alkaline (basic pH) proteins, and their positive charges allow them to associate with DNA.

Histones have many arginine and lysine amino acids which are positively charged. Hence Histones are positively charged proteins that facilitate the packing of DNA into condensed chromatin fibers.
