Abstract: There are many small non-coding RNA in the organisms. They through complete or incomplete complementary base pairingwith target mRNA, leading to mRNA breakage or translational repression, so as to achieve the purpose of the regulation of gene expression.These small RNA composed the highly complex RNA regulatory networks in cells, and play an important role in the physiological activity ofthe biological process of growth and development. Endogenous small RNA including miRNA, siRNA, and piRNA three categories, the articleoutlines three small RNA biogenesis, mechanism, and function research progress.
