The widened nucleoside components of double-wide DNA (yyDNA). A. Nucleosides 1 and 2, which are naphtho-homologated forms of deoxyuridine and deoxycytidine. B. Proposed structures of yyDNA base pairs (left), with analogous natural pairs at right. The distance from glycosidic C1′ to the opposite one in a pair is expected to be ca. 15.2 Å (compared with 10.4 Å in natural DNA).
