New Types of Solitonic Excitations in a Nonlinear Helicoidal Model of DNA and their Biological Significance
A. N. Bugay and G. F. Aru

A previously unexplored type of solitons in helicoidal nonlinear model for DNA is studied. A twist soliton represents a localized overtwist of DNA double helix propagating along with compression of hydrogen bonds between base pairs. Such solitons can be analytically described within the framework of Korteweg-de Vries equation.

Key words: DNA, nonlinear dynamics, soliton
