On the syntactic structure and redundancy distribution of the genetic code.
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.
