Gene Expression (lac and trp operons) 1.) Complete the comparison of the lac Operon and trp Operons as a means of gene regulation in E. Coli Lac Operon Trp Operon Used for catabolic or anabolic reactions? Inducible or repressible? Regulates production of: Number of genes and how they are controlled What binds to the operator/when does this occur/inducer, repressor or corepressor? High levels of what substance affects the operon and how? 2. Why are genes under regulation? 3. What makes up an operon? 4. What is the function of the promoter ? 5. What is the function of the operator?
