Sequence disorder-induced first order phase transition in confined polyelectrolytes
V. Stepanyan, A. Badasyan, V. Morozov +2
We consider a statistical mechanical model of a generic flexible polyelectrolyte, comprised of identically charged monomers with long range electrostatic interactions, and short-ra…
Microscopic formulation of the Zimm-Bragg model for the helix-coil transition
A. V. Badasyan, A. Giacometti, Y. Sh. Mamasakhlisov +2
A microscopic spin model is proposed for the phenomenological Zimm-Bragg model for the helix-coil transition in biopolymers. This model is shown to provide the same thermophysical…
Stacking and Hydrogen Bonding. DNA Cooperativity at Melting
Vladimir F. Morozov, Artem V. Badasyan, Arsen V. Grigoryan +2
By taking into account base-base stacking interactions we improve the Generalized Model of Polypeptide Chain (GMPC). Based on a one-dimensional Potts-like model with many-particle…
Helix-coil Transition in Closed Circular DNA
V. F. Morozov, Shura Hayryan, E. Sh. Mamasakhlisov +3
A simplified model for the closed circular DNA (ccDNA) is proposed to describe some specific features of the helix-coil transition in such molecule. The Hamiltonian of ccDNA is rel…
