DOUBLE SPIRALS IN STRUCTURES OF INORGANIC COMPOUNDS. V.M. Talanov, Chemical Department, State Technical University, Novocherkassk, 346400 Russia

Problem of uniqueness of albuminous-nucleinic way of organization of life is fundamental problem of natural sciences. Important aspect of this problem is existence in inorganic substance structures fragments which are the similar double spirale of DNA: Different types of double spiral were predicted as the result of theoretical calculations ordered spinel structures [1,2] and then were found in structures of different classes of inorganic compounds [3, 4 ] . The chain of inorganic double spirals are complementary, there are simple conformity between atoms of different spirals. Hence, these double spirals are not moleculars. They are bound in a complicated way. Inorganic double spirals form hard framework thanks to strong ionic-covalent bonds not able, certainly, to self-reproduction. It may be thought, that chemical evolution led to replicational systems of genetic colding not at once. On the first stages of chemical evolution structurees of inorganic substances could be matrices for abiogenic synthesis of DNA.
