Model 59 bp duplexes used in this study. (A) System TRY and (B) System TRYi. Sequence of the duplexes. The triple helix site is in bold and the same cleavage site b is indicated in red and underlined. The nomenclature of site b is as follows. The strand of the duplex, R or Y, is indicated as superscript followed by the side of the triple helix, 5′ or 3′, on which the site is located. For example, b^R5′ stands for a site b positioned on the R strand of the duplex and on the 5′ side of the triplex end. Numbers indicate the other cleavage sites.
