| abstract |
An object of the present invention is to provide a new nucleic acid molecule that can be easily and efficiently produced and can suppress gene expression. A single-stranded nucleic acid molecule comprising an expression suppressing sequence that suppresses expression of a target gene, comprising a region (X), a linker region (Lx), and a region (Xc), wherein the region (Xc) and the region (Xc) The linker region (Lx) is linked to the region, the region (Xc) is complementary to the region (X), and at least one of the region (X) and the region (Xc) A molecule comprising an expression suppression sequence, wherein the linker region (Lx) contains an atomic group derived from an amino acid. According to this single-stranded nucleic acid molecule, the expression of the target gene can be suppressed. |
