Sažetak
The algorithms and equations that define and link circular coding properties of the genetic code and amino acid structural properties are derived considering the model of Cantor dynamics based automaton. It is shown that the model defines unifying concept of the genetic code that incorporates Crick's code without comma and evolutionary code concept. Arithmetic for codes is defined via number theory results in coding theory, Smale horseshoe map and dynamics on fractal lattices. The method has been denoted SCA and defined with respect to the principles of molecular recognition theory, Grafstein's hypothesis of the stereochemical origins of the genetic code and Siemion's mutation ring. Underlying Fibonacci dynamics is extracted and mathematically defined considering Cantor set and Farey tree projections. Two digit specification of the codon positions, by means of the binary group subdivision, is particularly analysed with respect to octal coding and defined according to the purine-pyrimidine and strong-week H bonding discrimination principles.
