Guanine anchoring : a strategy for specific targeting of a G-quadruplex using short PNA, LNA and DNA molecules
Two separate structural elements of a G-quadruplex (G4), a vacant site and a flanking single-strand, provide an opportunity for specific targeting of a particular G4 structure via dual recognition. Here, we show that a short peptide nucleic acid (PNA) can specifically recognize and bind to a G4 at s...
