How do mirnas function in controlling gene expression? view available hint(s) how do mirnas function in controlling gene expression? by binding to dna and preventing transcription of certain genes?

Answer 1

I believe the miRNAs control gene expression by binding to mRNAs and degrading them or blocking their translation. The microRNAs are short non coding RNAs which function to regulate the process of gene expression. They bind to the 3-UTR of the target mRNAs and repress the production of protein by destabilizing the mRNA and translational silencing.
