Abstract: 

In this paper we consider a modified Peyrard–Bishop model with asymmetric doublewell interaction potential of nucleotides and dissipation. It is shown that at the certain value of dissipation coefficient the model solution takes the form of a kink. In terms of DNA molecule it describes the transition between two stable conformational states of DNA molecules – B–A transition.

Key words: 
DNA
