Structural characterization of quadruplex DNA with in-cell EPR approaches.

Abstract

Guanosine-rich DNA sequences have the potential to adopt four-stranded conformations termed quadruplexes. The chromosomes of higher organisms are capped by so-called telomeres that are composed of repeats of the sequence TTAGGG. Up to 200 nucleotides of the G-rich strand form an overhang that is suspected to fold into intramolecular G-quadruplexes. Since… (More)
