About important parameters of mathematical models of secondary and tertiary structures of molecules of ribonucleic acids (RNA)

The most important parameters of mathematical models of secondary and tertiary structures of molecules of ribonucleic acids (RNA) are described in this work. A severe quantitative estimation of a variety of possible secondary structures of RNA molecules is given. A task of identification of the tertiary structure model's parameters based on the structures of real transport RNAs received by a method of the X-Ray analysis is put. The first stage of this task (determination of geometrical parameters of two-spiral sites of tertiary structure of an RNA molecule) is solved on the basis of the X-Ray data on the form of a yeast phenilalanine transport RNA.
