Histone proteins contain internal cores that are hydrophobic and surface amino acids that are positively charged. Which of the following characteristics of DNA would best support tight binding between DNA and histones?
A) the ring structures in DNA bases that disperse charge promote hydrophobic interactions with histone cores
B) DNA 5' and 3' ends have negative charge responsible for stabilizing interactions with histone surfaces
C) the DNA backbone has a net negative charge that forms ionic bonds with histones
D) the 3.4 nm per helical turn in DNA fits around the spherical shape of the histones
