In this article, we define and analyse an extremely high amplitude (EHA) mode in DNA dynamics. The dynamics of a DNA chain is described by the Peyrard-Bishop-Dauxois model. We show that a local opening of the DNA chain in a process of m-RNA transcription is the EHA behaviour. Also, we point out that the helicoidal structure brings about the possibility for the EHA mode to occur.
