[Possible step in abiogenic molecular evolution]

Studies of peculiarities of sublimation of frozen solutions in small concentrations are described. Threadlike structures were revealed, whose formation can be explained by the development of spiral dislocations and aggregations of solved structure molecules into monomeric sequences of considerable length (up to 10(11) links). Possible coordination of molecules during the arrangement of closely located sequences from different biomonomeres is discussed. A hypothesis about sublimation mechanism of the organization of primary structure of macromolecules of the living matter is substantiated. This mechanism explains the appearance of genetic code and stereohomogeneity.
