Dependence of nucleotide physical properties on their placement in codons and determinative degree

Abstract

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.Comment: 13 pages, 8 figures, PD
