Before revision:  The states result from large fluctuations of a duplex and have a great influence on a wide range of biochemical processes , including electric charge transfer in DNA  . A comparative analysis of kinetic and thermodynamic experimental data on  DNA open states has been performed for a wide temperature range . Apparent contradictions between the data of different experiments have been explained.
