Vacuum ultraviolet circular dichroism as an indicator of helical handedness in nucleic acids.

Abstract

Calculated circular dichroism spectra are presented for double-stranded polynucleotides of regular sequences in A-RNA, A-DNA, B-DNA, and Z-DNA conformations. Quantum mechanical matrix method calculations were carried out in the near and vacuum ultraviolet regions. In the near UV, the calculated spectra agreed qualitatively with the measured spectra. However in the far and vacuum UV, the calculated CD compared nearly quantitatively with the experimental spectra. The calculations show that the sign of the CD in the vacuum UV, in contrast to that in the near UV, can be correlated with the handedness of the helix.
