Symmetry Analysis Of Genetic Code And Determinative Degree (in Russian)
  A three-dimensional model of the genetic vocabulary is proposed in terms of determinative degree, an introduced characteristic of nucleotide, which reflects absolute difference between purin and pyrimidin bases in one DNA strand. In the fremework of this model manifest symmetry and group properties are described. It is proposed to use the determinative degree of codons to analyze genetic texts, and to explain the biological sense of various functional regions of DNA.
