RNAi is a mechanism for regulating gene expression. It utilizes small microRNAs (miRNAs) transcribed in the genome of a particular organism. miRNAs can do which of the following? cause the degredation of mRNAs from particular genes directly block the reading of mRNA codons by tRNA anticodons alter the binding of tRNA to the ribosome alter the binding of repressor protein to the operator of prokaryotic genes
