[Classical and non-classical DNA conformations].
All possible right and left double helical structures which may exist in short fragments as well in polymeric DNA have been obtained on the basis of a developed rigorous and accurate method of conformational analysis of DNA. In polymeric DNA only right regular double helices are possible with preference of B-form that is the main biological form of DNA. In contrast, for short fragments the left and right helices have practically the same energies providing some physical ground for side-by-side form, which biologically is possible as a recombination form and maybe as a replication form.
