Analogs of DNA containing sulfides, sulfoxides, and sulfones as linking groups between subunits capable of forming bonds with natural oligonucleotides are described. The analogs are lipophilic, stable to chemical degradation under a wide range of conditions and stable to enzymatic degradation in vivo.
