    • (c) Apart from hydrogen bonding and stacking, the other two forces that have been implicated in the overall helix stabilization are phosphate repulsions and conformational entropy; see ref 1b. We have, however, recently found that attractive electrostatic interactions among the stacked nearest-neighbors (see refs 1d-f) play a dominant role in the self-organization of the single-stranded RNA and DNA, which we believe will even be stronger in the duplexes because of the gain in enthalpy due to hydrogen bonding.
