title: A new class of DNA quadruplexes formed by oligodeoxyribonucleotides containing a 3'-3' or 5'-5' inversion of polarity site.
abstract: Unprecedented DNA quadruplex structures containing a 3'-3' or 5'-5' inversion of polarity site in the G-tract are presented; the quadruplexes are characterized by different elements of symmetry and glycosidic angle conformations.
