Relish is the trаnscriptiоn fаctоr thаt increases the transcriptiоn of Anti-Microbial Peptide (AMP) gene expression in flies. You want to use RNAi to decrease the expression of relish in photoreceptor neurons to see if this modifies neurodegeneration in the fly model of Alzheimer’s disease we discussed in class. You will use the Gal4-UAS system and make transgenic flies. You have the following DNA sequences: The Upstream Activating Sequence (UAS) The Gal4 sequence (GAL4) A “promoter” sequence that is used only in Drosophila photoreceptor neurons (GMR) A transgene that encodes an RNAi against Drosophila relish A transgene that encodes a mutant version of human tau (V377M) Arrange these sequences in the genomes of the two flies shown below so that neither fly expresses relish RNAi or tau(V377M), but when mated, these flies can generate progeny that express RNAi against relish and tau(V377M) only in photoreceptors. The DNA sequence in box A would be [GMR] The DNA sequence in box B would be [Gal4] The DNA sequence in box C would be [UAS] The DNA sequence in box D would be [relish] The DNA sequence in box E would be [UAS2] If you wanted to change the expression of relish and tau to all cells of the brain, which sequence would you need to change? [A]
