Phys. Rev. E 66, 016614 (2002) [14 pages]Nonlinear dynamics of topological solitons in DNAReceived 21 November 2001; revised 1 April 2002; published 29 July 2002 Dynamics of topological solitons describing open states in the DNA double helix are studied in the framework of a model that takes into account asymmetry of the helix. It is shown that three types of topological solitons can occur in the DNA double chain. Interaction between the solitons, their interactions with the chain inhomogeneities, and stability of the solitons with respect to thermal oscillations are investigated. © 2002 The American Physical Society URL:
