This multi-pаrt questiоn аims tо reveаl hоw the expression of a gene can be regulated by a non-coding, regulatory micro RNA (miRNA) as part of an RNA Interference gene regulation mechanism. Please use Parts A, B, C to divide your answers. Part A. Begin with a brief description of how a cell could decide whether a miRNA should be expressed or not- i.e. where do they come from? Part B. How is the miRNA processed for integration into a functional ‘RISC' or 'RITS’ complex. Include specific names of the enzymes and their target molecules. Part C. Assuming the miRNA becomes part of both RISC and RITS complexes, explain how the miRNA is likely to suppress expression of its target gene if it is part of a RISC or RITS complex, respectively.
