Prior to 1953 William Astbury, Linus Pauling, Robert Corey and Rosalind Franklin were all suggesting models in which the phosphate chains were attached by means of the hydrogen bond. It was only with the onset of Crick and Watson’s proposed structure and their subsequent enoblement to the pantheon some ten years later that glycosidic/covalent bonds become triumphant. Not altogether unsurprising really… the nonsensical architecture of their proposal could not possibly sustain itself without some pretty hefty bonds. Indeed every molecule in their model has to held in position by clamps and ingenuity rather than naturally falling into position by means of natural architecture and geometry.
