Sum of rank preferences for a selection of amino acids and dinucleotides with respect to proportion of simulation time spent within 5 Å, for (A) whole dinucleotide (B) ring nitrogens, adjusted for molecular volumes. If all amino acids had their cognate nucleotides as their best binding partner, this gives the lowest score. Red = bases 1 and 2, anticodonic dinucleotide. Green = bases 1 and 2, codonic dinucleotide. Left of red line is the top 5% of randomised assignments.
