["Phantom" structure of solvents and packing of dual-chain nucleic acid molecules in liquid crystal dispersion...

The properties of mesomorphic dispersions of double-stranded nucleic acids were studied. A comparison of these properties indicates that their diversity cannot be explained unambiguously in terms of the conception of Van-der-Waals interactions in particles of mesomorphic dispersions without regard for the specific properties of the solvent, water, in the vicinity of adjacent nucleic acid molecules. It was assumed that, with small distances between the molecules of nucleic acids, a specific "phantom" structure of the solvent appears in their vicinity, which acts as an elastic medium that modifies the interactions between nucleic acid molecules and as a medium in which a collective tunneling of protons can occur. The combination of the two effects determines the "recognition" of nucliec acid molecules and the stabilization of the cholesteric structure of mesomorphic dispersions of nucleic acids.
