WebRemaining single-stranded miRNA or siRNA is complementary to specific mRNAs that will be silenced, so they act as a guide that cause RISC to recognize and bind to such mRNA molecules. RISC binds to mRNA a. RICS may inhibit translation without degrading mRNA (usually miRNA bc they are partially complementary to their target mRNAs) b. WebViral vectors can also be used, or the pre-miRNA itself can be transfected. Usually, the associated companies offer the pre-miRNA precursor molecule, a miRNA mimic that is chemically synthesized as a modified double-stranded oligonucleotide [84].
