pubpic2000bergerRelying on only interbase hydrophobic packing for bonding, several unnatural nucleobases are reported that form selective and stable self-pairs in duplex DNA. These unnatural nucleobases should make it possible to increase the stringency and information content of hybridization or encoding experiments.
