RNA interference (RNAi) has become a powerful tool in molecular biology research. For this week's discussion, describe an experiment or application where RNAi has been used to suppress expression of a target gene. If you are describing an experiment, be sure to explain the background, the hypothesis and the results. If you are describing an application, make sure to explain why the organism and gene in question were targeted. No need to cite the source. just provide the link as to where the information was taken. for eg https://www.ncbi.nlm.nih.gov/pmc/articles/PMC309050/). please make sure the information matches with the link provided.
