Eukaryotic Gene Regulation (in Hindi)

The mechanism of action of both siRNAs and mIRNAs is mediated by Dicer and RISC complex. Dicer will cleave either pre-miRNAs or dsRNA to generate the final active molecules. As already pointed out when the complementarity between the acting RNA and the target is complete, we have a mRNA degradation (siRNA) induced by Ago2 that harbors endonuclease activity. In the case of miRNAs the complementarity is only partial with the target and we got translational repression mediated by RISC. Interestingly in plants miRNA are different from a animals, showing almost perfect matching with their targets and in this case they act as siRNAs.
