Core features of miRNA and siRNA silencing
In general:
– miRNAs- regulators of endogenous genes
– siRNAs- defenders of genome integrity in response to foreign or invasive nucleic acids such as viruses, transposons, and transgenes.
Single-stranded forms of both miRNAs and siRNAs are found to associate with effector assemblies known as RNA-induced silencing complexes (RISCs).
