Abstract:In this article the physicochemical and biological properties of sequence-related G-quadruplex forming oligonucleotides in RNA and DNA series are analyzed and compared. The intermolecular G-quadruplexes vary in loop length, number of G-tetrads and homogeneity of the core. Our studies show that even slight variations in sequence initiate certain changes of G-quadruplex properties. DNA G-quadruplexes are less thermally stable than their RNA counterparts, more topologically diversified and are better candidates a… Show more
