How does mirna stop protein synthesis
WebWhat is miRNA and how does it work? miRNAs (microRNAs) are short non-coding RNAs that regulate gene expression post-transcriptionally. They generally bind to the 3′-UTR … WebThe miRNA directs the protein complex to “matching” mRNA molecules (ones that form base pairs with the miRNA). When the RNA-protein complex binds: If the miRNA and its target match perfectly, an enzyme in the RNA …
