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.
