Prior to 1953 William Astbury, Linus Pauling, Robert Corey and Rosalind Franklin were all suggesting models in which the phosphate chains were attached by the means of the hydrogen bond. Glycosidic/covalent bonds become triumphant only with the acceptance of Crick & Watson's architecture. Their proposal would struggle to sustain itself without some pretty hefty bonds. Indeed every molecule in their model is held in position by clamp’s, ingenuity and distinctly unnatural forces instead of falling into position by means of a natural geochemical architecture.
