Unravelling the double helix illustration to show the structure of the dna double helix image credit: genome research limited from structure to function. Introduction the stability of the dna double helix depends on a fine balance of interactions including hydrogen bonds between bases, hydrogen bonds between bases and surrounding water molecules, and base-stacking interactions between adjacent bases. Transcript: the structure of dna, that watson and crick discovered, suggests how genetic information is passed on before a cell divides, the double helix unwinds and the two strands of the dna molecule in the nucleus separate.
