Answer the following problems assuming that gene Z is regulated by the following regulatory network. Presume that B, C and D are proteins each with their own gene and that the interactions are showing how the proteins regulate the specific promoters. Assume that stimulus A is a metabolite and the arrow shows how its binding to protein B influences that protein's DNA binding activity. Assume that the organism is haploid.
