Abstract
The dispersions were obtained as a result of phase exclusion of the DNA molecules from aqueous-salt-PEG-containing solutions. The CD spectra have shown cholesteric and hexagonal packing of the DNA in single dispersion particles at room temperature. The phase transition of the hexagonal → the “re-entrant” cholesteric packing of DNA takes place at elevated temperature. The texture of the “re-entrant” phase does not demonstrate attributes of DNA cholesteric phase. Alternative reasons of such discrepancy are discussed in the presented Letter.
