Hydrophobia apparently is why D.N.A. strands are held together according to a new discovery in Sweden. https://scitechdaily.com/scientists-were-wrong-about-dna-it-is-actually-held-together-by-hydrophobic-forces/
With water in a cell surrounding the strands a hydrophobia inducing protein for nitrogen bases draws genes together- instead of hydrogen bonds- cringing together away from the sloshing, turbulent cellular sea. A coherent inner core stays together amidst froshy wash of dissolution.
