Histones carry a slight positive charge, and DNA carries a slight negative charge. Since opposite charges attract, the DNA is pulled in toward the histones. A nucleosome is a segment of the DNA wrapped around a core of histones.

DNA is not any of these. Anions and cations refer to ions, which are charged groups of atoms, not molecules. DNA is made up of both cations and anions.
However, DNA is also not neutral, because it has a slight negative charge.

1st person is WRONG!!!!!!!!!!!!!!!!!!
DNA, despite the popular belief of being neutral, is NEGATIVE (anion)! we're talking about a nucleic acid, which is has an acidic pH.
otherwise, our complete studies of the HGP and DNA sequencing wouldnt be possible, since electrophesis (sp) wouldn't be possible.
in simple terms- we wouldn't know where are genes were located if DNA was neutral.
