It is intended to provide a polynucleotide that is resistant to RNase and has an RNA interference effect, etc. The present invention provides a single-stranded polynucleotide that is derived from a double-stranded polynucleotide comprising a sense strand polynucleotide corresponding to a target gene, and an antisense strand polynucleotide having a nucleotide sequence complementary to the sense strand polynucleotide, and has a structure in which the 5'-end of the antisense strand and the 3'-end of the sense strand are linked via a phenyl group-containing linker to form a phosphodiester structure at each of these ends.
本发明旨在提供一种能抗 RNase 并具有 RNA 干扰作用的多核苷酸等。本发明提供了一种由双链多核苷酸衍生的单链多核苷酸,双链多核苷酸包括与靶基因相对应的有义链多核苷酸和具有与有义链多核苷酸互补的核苷酸序列的反义链多核苷酸、其结构是反义链的 5'-端和有义链的 3'-端通过含苯基的连接体连接,在这两端分别形成磷酸二酯结构。
