The present invention provides a double-stranded polynucleotide having a sense strand polynucleotide consisting of a nucleotide sequence complementary to a target sequence in a target gene, and an antisense strand polynucleotide having a nucleotide sequence complementary to the sense strand polynucleotide, wherein an aryl or heteroaryl compound is bound to a phosphate group at the 5′-end of the antisense strand polynucleotide.
本发明提供了一种双链聚核苷酸,其具有一个具有与目标
基因中的目标序列互补的核苷酸序列的正链聚核苷酸,以及一个具有与正链聚核苷酸互补的核苷酸序列的反义链聚核苷酸,其中一种芳基或杂环芳基化合物结合到反义链聚核苷酸的5'-末端的
磷酸基团上。
