G-quadruplexes, four-stranded structures formed by Guanine-rich nucleic acids, are implicated in many physiological and pathological processes. G-quadruplex-forming sequences are abundant in genomic DNA, and G-quadruplexes have recently been shown to exist in the genome of mammalian cells. However, how G-quadruplexes are formed in the genomes remains(More)
G-quadruplex structures formed by guanine-rich nucleic acids are implicated in essential physiological and pathological processes and nanodevices. G-quadruplexes are normally composed of four Gn (n ≥ 3) tracts assembled into a core of multiple stacked G-quartet layers. By dimethyl sulfate footprinting, circular dichroism spectroscopy, thermal melting, and(More)
