Hydrophobic forces hold DNA

A research collaboration between biochemists mainly at Chalmers University in Sweden and the University of California at Berkeley report a newly discovered structural property of DNA.  “The main stabilizer of the DNA double helix is not the base-pair hydrogen bonds but coin-pile stacking of base pairs, whose hydrophobic cohesion, requiring abundant water, indirectly makes the DNA interior dry so that hydrogen bonds can exert full recognition power.
