[The origin of the eukaryotic cell. IV. The general hypothesis of the autogenous origin of eukaryotes].

The general hypothesis of autogenous (non-symbiotic) origin of the eukaryotic cell summarises some hypotheses explaining possible ways of the origin of main components and organelles of such a cell (the primary unicellular protist). Six hypothesises are suggested. Arising of the eukaryotic surface membrane of protist (cell) as a result of modification of its lipidoacidic composition, when most of synblocks and ensembles of eukaryotic enzymes sink into the cytoplasm (due to membrane vesiculation). Establishment of eukaryotic cytoplasm on the basis of successive formation of two locomotory-supporting apparates: the primary one (microtrabecular system), and the second one (cytoskeleton). Arising of the nucleus from a polyheteronomous nucleoid of proeukaryotes. A combinatorical hypothesis of mitosis formation. Polyheteronucleoid hypothesis of the origin of the mitochondria and chloroplasts. Arising of the flagellum from the contractile tentacle-like organelle, whose axoneme is made of single microtubules. A close interrelation and interaction in the process of evolution is noted between surface membranes, the cytoplasm and the nucleus. In accord a principles of block-construction and heterochrony (see: Seravin, 1986r), the author explains the preservation of prokaryotic signs of organization in some components (and organelles) of eukaryotic cell (and protists).
