چکیده انگلیسی
DNA duplexes are known to be quite stable in the condensed phase but recent mass spectrometry results have shown that DNA complexes are also stable (at least for a limited time) in the gas phase. However, very little is known about the overall shape of the complexes in a solvent-free environment and what factors influence that shape. In this article, we present recent ion mobility and molecular modeling results that address some issues concerning the gas-phase conformations of DNA duplexes. Examples include the effect of metal ions on Watson-Crick base pairing, investigating the onset of helicity in duplexes as a function of strand length, comparison of the stability of C·G and A·T base pairs, and examining the formation of quadruplex structures.
