Figure 1:

Canonical miRNA biogenesis pathways in animals and plants. miRNA synthesis begins with the transcription of pri-miRNAs, which are then cleaved into pre-miRNAs by different enzymes. These precursors are subsequently processed into mature miRNAs—within the nucleus in plants, but in the cytoplasm in animals. The resulting miRNA duplexes are then loaded onto different AGO proteins, with distinct AGO associations in plants versus animals. AGO, argonaute; miRNAs, microRNAs; pre-miRNAs, precursor miRNAs; pri-miRNAs, primary miRNAs.

Distinguishing characteristics inherent to miRNA and siRNA_

Feature miRNA siRNA
Origin Endogenous Endogenous and exogenous
Structure Hairpin precursor Long dsRNA
Processing enzymes Dicer1 or DCL1 (in nucleus, mostly) Dicer2 or DCL4 (also DCL2, DCL3 depending on siRNA class)
Target complementarity Partial (often with central mismatches) or near perfect Usually perfect or near-perfect
Function Post-transcriptional gene regulation (mRNA degradation or translational inhibition) Gene silencing, antiviral defense, transposon suppression, RdDM
Target specificity Often targets multiple genes in the same family Highly specific to one or few targets
