Biopolymers and cells in dimension of microbial community architecture. 3. Microcenosis, cell, biopolymers – what they are?

The published experimental data on functional differences in organization and functioning of genetic materials between eukaryotes and prokaryotes have been analyzed. A new conception of both specific status of prokaryotic genome and uncertainty of the cell definition has been proposed. It is based on the information about multitude and diversity of the channels for horizontal gene transfers, taking into account the fertility characteristics, and the facts of formation of some bodies less than 0,2 µm in size under different conditions. The question is: what are the forms which cannot be cultivated in laboratory and at the same time prevail in natural substrates?
