PP‐1atoms and molecules, but also their whole groups can be disposed. The scheme ofabiogenesis in the quataron hypothesis looks as follows:Formation of quatarons in atmosphere ‐ capture and conservation (in cavities ofquatarons) of H, O, C, N and P atoms necessary for formation of nitrogenous bases,phosphatic groups, D‐riboze etc. ‐ condensation of quatarons with "guest" atoms, molecules(possibly with already formed functional groups) ‐ interaction and aggregation of "guest"atoms and molecules, nitrogenous compounds in condensed water medium, ‐ polymerizationand formation of DNA and RNA molecules.Thus, according to these hypotheses abiogenic assemblage of complex biomolecules andthe origin of life are not casual processes, but a consequence of quite real physical andchemical processes. Both hypotheses demand presence of three‐dimensional cavities (nanoreactors)which sizes coincide with the corresponding sizes of functional groups ofcomponent parts of DNA and RNA molecules. Processes of usual assemblage of molecules inthat or other case, possibly, begin in atmosphere from the moment of formation of methaneor water quatarons.The comparative analysis of hydrate and quataron hypotheses of the origin of thesimplest elements of living matter testifies to their deep generality and possible parallelrealization. Both hypotheses allow to propose ways of abiogenic assemblage of DNA andRNA and thus to reveal new ways to disclosing the secrets of the origin of life. At least, boththese hypotheses partially remove the problem of extremely small probability of selfassemblageof such complex biopolymers as DNA and RNA during casual interactions ofseparate elements. According to these hypotheses the process of self‐assemblage becauseof preliminary self‐organization ceases to be completely casual. This is already theassemblage not from separate chemical elements, but from ready "bricks" and "blocks" ‐functional groups. As a result the formation of molecules of DNA and RNA type obtains thecharacteristics similar to cluster growth of crystals.The work is supported by programs of the Presidium and the Department of EarthSciences of the RAS, the RFBR (grant 11‐05‐00432‐а).[1].
