the base pairing motifs of the universal nucleoside 8-aza-7-deazapurin-6-amine N8-(2'-deoxyribofuranoside) 2 (adenine analogue) and that of the 2,6-diamino compound 1. Owing to the absence of an amino group on the nucleoside 3a the low stability of oligonucleotide duplexes incorporating this compound opposite to the four canonical DNA-constituents indicate hydrogen bonding and base pairing for the universal
