    • For practical reasons, these experiments were performed with the 2′-deoxy-NTPs (i.e., dATP and d2AP-TP, where 2AP is 2-aminopurine). Because dATP is almost as efficient a substrate as ATP (see below), the 2′-deoxy modification of d2AP-TP is not responsible for its poor reactivity as a substrate relative to dATP.

    • A modest amount of ligation activity was observed when GTP or ITP was used along with A in the deoxyribozyme see the Supporting Information, This indicates that non-Watson-Crick interactions between the NTP substrate and deoxyribozyme are possible, albeit much less productive than Watson-Crick interactions

    • Use of dGTP in place of GTP led to a similar amount of the A-G product but no detectable A-GG product. One interpretation is that the template-synthesized GG dinucleotide is 2′-5′-linked. Alternatively, the GTP 2′-OH group could be required for templated synthesis of a 3′-5′-linked GG dinucleotide. These two possibilities cannot be distinguished on the basis of the available data
