| Abstract: | DsRNA gets proceed into siRNA by an eneyme called Dicer, siRNA then assemble into activated complexes known as RNA-induced silencing complex (RISC). DsRNA can trigger chromation concentrating, gene silencing and DNA methylation, and interfere with protein synthesis and so forth. Gene silencing triggered by RNAi have advantages of being high efficiency, peculiar, simple, direct and so on. It may supply new thought and method for the study of gene expression in cell, and it also could be a potential strategy for the treatment of disease in clinica. |
| Keywords: | dsRNA RNA-induced silencing complex (RISC) gene silencing |
