miRNA is an important regulatory molecule that helps cells defend against double-stranded RNA viruses. When cells encounter viral RNA, they produce miRNA which can then bind to and degrade the viral RNA, preventing further viral replication. miRNA does not induce the production of more mRNA or artificially turn on gene expression, nor is it used by viruses to stop the production of new proteins.
