Study of DNA films by the CD, X-ray and polarization microscopy techniques
Institute of Molecular Genetics, USSR Academy of Sciences Kurchatov Sq., 123182, Moscow, USSR
Received October 23, 1980.
DNA films with
± CD spectra have been investigated. X-ray analysis has snown the sign of the
spectra to be independent of the secondary structure of DNA. The appearance of the
spectra is attended by the formation of a characteristic polygonal texture of the cholesteric type in the DNA film.
