1. The following image shows a mechanism in which gene expression activity is regulated by ligand. Arg RS-2 Teu Met RBS Ligand RBS hidden a. What is this kind of regulatory machnism called? b. Does it involve transcription or translation? c. What happens in the presence of the ligand? d. What happens in the absence of theligand? e. What do you think the genes that are regulated here - metabolic (breakdown) or anabolic (buildup) for the ligand? Explain

8. Yeast genes have cis-acting elements upstream oftheir promoters, similar to enhancers, called upstreamactivating sequences or UASs. Several target genes involved in galactose utilization are regulated by onetype of UAS called UASG, which has four bindingsites for an activator called GAL4. Two target genesregulated by UASG are GAL7 and GAL10. The GAL80 protein is an indirect repressor of GAL7 and GAL10transcription: At UASG, GAL80 binds to GAL4 protein and blocks GAL4’s activation domain. In thepresence of galactose, GAL80 no longer binds GAL4.In which gene(s) (GAL4 and/or GAL80) shouldyou be able to isolate mutations that allow the constitutive expression of the target genes GAL7 andGAL10 in the absence of galactose? In each case,what characteristics of the protein would the mutationdisrupt?
