    "abstract": "Why is the genetic code the way it is? The most successful theory states that\nthe codon assignments minimise the effects of errors arising in primordial\nliving systems. Here a transversion is reported that leaves invariant\ndegeneracy in the genetic code. A model was established to address the\nquestion: How should sets of synonymous codons be chosen to minimise the\ndeleterious effects of non synonymous substitutions? It is shown that the\narithmetic theory of quadratic forms provides the framework for degeneracy in\nthe genetic code.",
