Hydrogen-bonded nanotubes as a model for DNA transcription.
Using the energy asymmetries in the hydrogen-bonded structures, the model is formulated explaining melting of DNA double chain and also explaining further decay of only one of the obtained single chains. The model is similar to the Scott's model of alpha-helix, where the spiral is substituted with interacting discs. The explanation of mentioned DNA transformation is based on the estimate of free energy of discs with an even number of hydrogen bonds, and an estimate of melting point temperature for the subsystem of odd index fibers and transition temperature of the subsystem of even index fibers.
