The paper considers the order-disorder transition in a sequence of two varieties of repeating units. It is shown that the reduced free energy converges to the limit at the chain length of more than 3000. The origination of the fine structure of diffe

One of the major interaction mechanisms between carbon nanotubes (CNT) and DNA is $ \pi \mbox{-} \pi $ stacking, which is a van der Waals type of interaction. Attraction between the polycyclic aromatic surface elements of CNTs and the aromatic nucleo

The resistance of a monolayer of complexes of the double-stranded DNA with quantum dots were computed. It was shown that with the non-competitive DNA hybridization and in the presence of monovalent positively charged ligands in the solution, a decrea

The main goal of this paper is the investigation of helix–coil transition in heteropolymers by means of straight calculation of partition function, free energy, helicity degree and other characteristics of transition on the bases of generalized mod

The factors are analyzed, which influence both the hybridization thermodynamics and the DNA/DNA-duplex stability. The non-competitive hybridization of the DNA as well as the competitive hybridization on the surface are investigated. It is shown that

Within the frameworks of generalized model of polypeptide chain (GMPC) the concentrational behavior of helix-coil transition temperature of biopolymer in two-component solvent was observed on the simplest models. It is shown that if the solvent and t

Within the frameworks of Generalized Model ofPolypeptide Chain (GMPC) the influence of the ligands interacting by different ways in the helix-coil transition is studied. It is shown that the model is reduced to the base model by converting the energy

We consider the theory of helix-coil transition in heteropolymeric biopolymers with an arbitrary number of components in cases of heterogeneity with respect to both energy and number of conformations. The theory is based on the Generalized Model of P

A theory of helix-coil transition in DNA, heteropolymeric with respect to energies of H-bond formation, is considered. The theory is based on the Generalized Model of Polypeptide Chain (GMPC) with employing the constrained annealing method. Expressio
