(A) Chemical structures of the G-quartet. (B) Schematic representation of the folding and melting of the intramolecular quadruplexes. The fluorophore and quencher are represented by the shaded and filled circles respectively. Although several different folded structures are possible, for simplicity only one antiparallel structure is shown. (C) Sequences of the oligonucleotides used in this work.
