Which of the Following is Most Critical for the Association

Question

Which of the following is most critical for the association between histones and DNA?
A)Histones are small proteins.
B)Histones are highly conserved.
C)There are at least five different types of histone proteins in every eukaryote.
D)Histones are positively charged.
E)Histones have hydrophobic patches on their surface.

Accepted Answer

Histones are positively charged due to the presence of amino acids like lysine and arginine. This positive charge forms electrostatic interactions with the negatively charged phosphate groups of DNA, making the association between histones and DNA critical.
