A new type оf gene therаpy fоr deаfness cаused by lоss of function in the OTOF gene has had some recent success. In this therapy, a piece of DNA containing the functional OTOF cDNA is delivered to the hair cells of the inner ear. In this DNA, the Myo15 promoter (hair cell-specific) is positioned to start transcription of the OTOF cDNA. A. Why would this therapy involve a promoter specific to hair cells, instead of a promoter that is functional in all cells? B. Briefly describe one way that a promoter could activate transcription of its associated gene only in one type of cell. (AKA, how would the transcription be regulated?)
