Development of methods for mathematical simulation of biological systems and building specific simulations is an important trend of bioinformatics development. Here we describe the method of generalized chemokinetic simulation generating flexible and adequate simulations of various biological systems. Adequate simulations of complex nonlinear gene(More)
The Evolutionary Constructor software has been used for computer simulation of the life and evolution of communities of unicellular haploid organisms (prokaryotic cells). Opposite trends of the community evolution (simplification and complication of the genome) have been studied. It has been demonstrated that species with reduced genomes tend to replace(More)
Prion diseases belong to a group of neurodegenerative disorders caused by conformational changes--destroying the alpha-helices--in prion proteins (PrP). We performed a phylogenetic analysis of 32 PrP sequences and restored the most probable evolutionary spectrum of amino acid substitutions. Although prion proteins are not too conserved judging from the(More)
Data on location of mobile elements mdg1, Dm412, copia, and B104 in 33 isogenic lines of Drosophila melanogaster has been processed by means of cluster analysis to reveal the relationship between the penetrance for bristle reduction and the distribution of mobile elements. The presence of two groups of sites specific for lines with contrasting penetrance(More)
Under investigation is congruent variation of movable elements, the "genome parasites" (GP), and genome proper, as the "host". Several differential equations are studied that describe the following situations. 1. GP is able to insert in free sites only, existing in autonomous stage (outside of the genome) limited time only. 2. GP inserts in free sites only,(More)
