METHOD OF SEARCHING FOR FUNCTIONAL NUCLEOTIDE MOLECULE

摘要

A universal method of searching for a nucleic acid capable of effectively inhibiting gene expression; a nucleic acid construct to be used in this method; a vector; and a kit for the above method. This method is characterized in that a nucleic acid construct, which is a nucleic acid construct having a promoter sequence, at least two gene sequences and a poly A signal sequence and in which the above-described at least two gene sequences are transcribed as a single molecule RNA and at least one gene sequence is in the translatable state while at least one gene sequence is encoded in the substantially untranslatable state, is constructed.
