ABSTRACT:
Replacement of the natural nucleotides with unnatural zwitterionic nucleotides having a cationic moiety tethered to the base (or analog thereof) results in oligodeoxynucleotides with diminished charge but undiminished ability to complex with DNA at low ionic strengths. We have now discovered that DNA can be made fully zwitterionic by introducing tethered cationic moieties to the bases without affecting duplex formation. The resulting oligonucleotides have the further advantages of being nuclease resistant.
