We investigated the phenomenon of ultrasonic cleavage of DNA by analyzing a large set of cleavage patterns of DNA restriction fragments using polyacrylamide gel electrophoresis. The cleavage intensity of individual phosphodiester bonds was found to depend on the nucleotide sequence and the position of the bond with respect to the ends of the fragment. The(More)
Next Generation Sequencing (NGS) technology is based on cutting DNA into small fragments, and their massive parallel sequencing. The multiple overlapping segments termed "reads" are assembled into a contiguous sequence. To reduce sequencing errors, every genome region should be sequenced several dozen times. This sequencing approach is based on the(More)
A method for studying the local inhomogeneities of DNA and its dynamics is proposed. The method is based on the combination of two procedures, splitting the DNA molecules by ultrasound and analysis of DNA fragments obtained by gel electrophoresis. The frequency of cleavage of internucleotide bonds was found to depend on the type of nucleotides forming the(More)
In this work we examine how protein structural changes are coupled with sequence variation in the course of evolution of a family of homologs. The sequence-structure correlation analysis performed on 81 homologous protein families shows that the majority of them exhibit statistically significant linear correlation between the measures of sequence and(More)
The authors analyze the individual variability of the agent of scabies in populations on individual patients and in foci of the disease. They define an elementary micropopulation and a focal population notions. A total of 763 females, collected from the hands of 100 patients with scabies were examined. The findings evidence that the degree of the chetoid(More)
We investigated a phenomenon of ultrasonic cleavage of DNA complexed with transition metal cations Ag(I), Cu(II) and Hg(II). We found the statistically significant dependence of relative intensity of cleavage on cation type and concentration. Each cation may cause two different types of distortion in the DNA double-helix depending on whether it binds to(More)
