Therapeutic oligonucleotide analogs which have improved nuclease resistance and improved cellular uptake are provided. Replacement of phosphorodiester inter-sugar linkages found in wild type oligomers with four atom linking groups forms unique di- and poly-nucleosides and nucleotides useful in regulating RNA expression and in therapeutics. Methods of synthesis and use are also disclosed.
