A nonlinear model describing DNA dynamics, called helicoidal Peyrard-Bishop model, is described. It is shown that the model can explain a local opening of a DNA helix during transcription. An impact of friction forces is also studied. It is pointed out that a role of viscosity is crucial for DNA-RNA transcription.
