Translated title of the contribution: Several possible conformational states of a homogeneous elastic polymeric chain

    Abstract

    A homogenous elastic macromolecule, the so-called persistent model is considered. Possible initiation of dense globular state in it with nematic orderliness of the chain elements is analysed. The entropy of such a system in an arbitrary state is calculated. It is shown that a relatively short rigid chain forms a thoroidal structure. With the chain elongation thor is increased, without changing its proportions. When the parameters are changed the thoroidal structure may turn into the conventional one-linkage one. Possible application of this model for solving the problem of trimeric package of nuclei acids is discussed in a few words.
