  1. Abbreviations: mod, modification; TP ODN, triazolylphosphonate oligodeoxynucleotide; x, 5′-TAGCAGCACATCATGGTTTACA-3′; x′, 5′-TGTAAACCATGATGTGCTGCTA-3′.
  2. The TP ODN sequences are defined in Table 1. All Tms represent an average of at least three experiments; ΔTm is the difference in Tm when compared with Tm of the unmodified duplex.
