title: On the syntactic structure and redundancy distribution of the genetic code.
abstract: By means of an algorithm for finding rules in data, it is shown that the genetic code may be written as a codon-tree, independent of amino acid assignments. Considering this tree as a structural description, a low-complexity, context-free grammar of the code is built and its grammar complexity and grammar redundancy calculated. The relationship between the codon-tree and the hierarchy of amino acid categorizations previously introduced by the author is investigated. Interpreting the obtained code's structure as a record of its evolution, some inferences about the divergences of the code series are made.
