Abstract A solitary wave propagation of deoxyribonucleic acid (DNA) double helices has been discussed. The stretch of the hydrogen bonds is considered as a nonlinear chain with cubic and quartic potential. The solitary wave solution can be obtained by using a homogeneous balance method. The characteristic parameters of solitary wave, such as the stretch amplitude and width are estimated. It is shown that the conformational transitions from B-DNA to A-DNA can occur in a certain condition.
