Figure 3: miRNA mediated regulation of translation at postinitiation stage. (a) Ribosome drop-off is the proposed mechanism where translation is initiated and miRNA directed ribosomes to inhibit the translation prematurely. (b) Other possible mechanisms of miRNA mediated translation repression are nascent polypeptides which are degraded by proteosomes.
