Jiménez-Montaño, Miguel A. A Markov information source for the syntactic characterization of amino acid substitutions in protein evolution. (English) Zbl 1324.92025 Symmetry Cult. Sci. 23, No. 3-4, 323-342 (2012). Summary: We introduce a theoretical model, which consists of a Markov information source that generates codon sequences, and from them amino acid sequences, that maintain the same or very similar functions and structures, as a direct consequence of the structure of the genetic code, and general physical chemical constraints. With the help of the model, we propose a codon dendrogram to describe a hierarchy of codon categorizations, which explain the pattern of frequent amino acid substitutions in short term evolution.
