  Various physical properties such as dipole moment, heat of formation and
energy of the most stable formation of nucleotides and bases were calculated by
PM3 (modified neglect of diatomic overlap, parametric method number 3) and AM1
(Austin model 1) methods. As distinct from previous calculations, for
nucleotides the interaction with neighbours is taken into account up to
gradient of convergence equaling 1. The dependences of these variables from the
place in the codon and the determinative degree were obtained. The difference
of these variables for codons and anticodons is shown.
