RNA interference (or RNAi) is a popular research tool used in biomedical research. It has great potential as it allows researchers to "knock down," or silence, genes of interest. For, example, it could be used to block expression of a gene that plays a role in a certain cancer. In the lab, researchers can design synthetic double stranded RNA that then binds the mRNA of interest and leads to its

destruction. Which mechanism within a cell also leads to mRNA destruction? Explain how this mechanism works. What will be an ideal response?
