Abstract

Oligonucleotide analogs are provided wherein phosphodiester inter-sugar linkages are replaced with four atom linking groups. Such linking groups include NR--C(O)--CH.sub.2 --CH.sub.2, NR--C(S)--CH.sub.2 --CH.sub.2, CH.sub.2 --NR--C(O)--CH.sub.2, CH.sub.2 --NR--C(S)--CH.sub.2, CH.sub.2 --CH.sub.2 --NR--C(O)--R--CH.sub.2, and CH.sub.2 --C(S)--NR--CH.sub.2. Methods for preparing and using these oligonucleotide analogs are also provided.
