The invention relates to oligonucleotides having alternating segments of sugar-modified nucleosides and 2′-deoxynucleosides, and uses thereof. The invention further related to oligonucleotides having alternating segments of sugar-modified nucleotides and 2′-deoxynucleotides, and uses thereof. Such uses include the preparation of antisense oligonucleotides and their use for the prevention or depletion of function of a target nucleic acid of interest, such as an RNA, in a system. Accordingly, and oligonucleotide of the invention is useful for therapeutic, analytical and diagnostic methods and uses, as well as component of compositions and commercial packages corresponding to such methods and uses.
