Figure 2. Guide to modified bases used in these studies. Adenine (ade), guanine (gua), 7-deaza-guanine (7deazaG), 7-deaza-adenine (7deazaA), nebularine (neb), inosine (ino), 2-aminopurine (2AP). Arrows indicate positions that are good hydrogen bond donors or acceptors. The nomenclature of each modified oligonucleotide starts with the base to be substituted, followed by its position from the 5' end of the sequence 5'-d(TTAGGGTTAGGG)-3', and then by the base substitution.
