DNA-RNA: Twenty-Sphere Models of DNA-RNA Compounds:
"Furthermore the 20-sphere (atoms), closest-packed, non-nucleated tetrahedron consists of five basic (because minimum limit), four-ball tetrahedra which, unlike their planar-faceted polyhedral counterpart tetrahedra, can be closest-packingly assembled without octahedronal complementation and because the octahedra are internal to the four-ball basic tetrahedra. It is further relevant to these considerations that the DNA-RNA code consists always and only of the four chemical compounds: guanidine, cytosine, adenine, and thiamine; and that the helix which they generate consists entirely of tetrahedra whose four constituents in all vast variety of combinations will always be the same tetrahelixes."
