WebHow does miRNA inhibit translation? MicroRNAs are small molecules that do not themselves encode proteins but bind to messenger RNAs that to do this. They act as gates for messenger RNAs and prevent their translation into proteins, but how they produce this effect and at what stage of protein synthesis they intervene has long been a mystery.
