The free nucleobases and mononucleotides of RNA do not form Watson-Crick base pairs in water, a fact that presents several challenges for the prebiotic synthesis of RNA. 2,6-Diaminopurine and adenosine-5'-monophosphate (AMP) are shown to form supra-molecular assemblies with cyanuric acid in water. These assemblies and their propensity to form liquid crystals suggest a possible means by which non-covalent structures might have originally selected the shape of the Watson-Crick base pairs.
