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

The melting of the DNA–ligand complex is considered theoretically for the ligands binding with the DNA by two mechanisms. The obtained results describe the experimentally observed behavior of such quantities as the denaturation degree and the corre

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

The Hamiltonian of the two-scale generalized model of the polypeptide chain is constructed for the case of combined solvent. It is shown that the partition function for the model with solvent equals to within unessential factor the partition function
