[Statistical characteristics of inhomogeneities of protein and chromation networks].
Natural textures (networks) are observed in many cases: the inter-cellular contact sites, endoplasmic reticulum membranes etc. The vast amount of experimental data was analyzed to produce the distribution histograms for the length of the segments in the protein and chromatin networks of different origin. The networks both from the eukaryotic cells and nucleis, as well as from E. coli and viruses are presented. Statistical analysis demonstrated that all experimentally observed histograms fit to the following formula: F(x) = (5(5)[4]) x x(4)x exp(-5x) where x =l/<l>, l- length of the network segment, and </> is the average length of the segment. In contrast to the Gaussian distribution, the distribution of the segments' lengths is markedly assymetrical. The shape of the distribution does not dependent on the origin of the analyzed network.
