Transcript
How Is Gene Expression Regulated in Prokaryotes? 1. Regarding the operons of prokaryotes: Draw an operon and label the promoter, operator, and genes that code for enzymes. Indicate the overall purpose of a operon and the specific function for each of the above regions. Explain how the lactose operon is related to nutrient availability; what does the regulatory gene do? 2. Compare the function of the trp operon to that of the lactose operon; how is each regulated? 3. Indicate the difference between an inducible operon and a repressible operon; how is this related to regulation of genes that synthesize a product vs. those that degrade a substrate.
