  In this paper it is shown that within a Combined Genetic Code Table, realized
through a combination of Watson-Crick Table and Codon Path Cube it exists,
without an exception, a strict distinction between two classes of enzymes
aminoacyl-tRNA synthetases, corresponding two classes of amino acids and
belonging codons. By this, the distinction itself is followed by a strict
balance of atom number within two subclasses of class I as well as two
subclasses of class II of amino acids.
