Welcome back — been a while! Let's pick up where you left off. The question asks what the 'z' gene in the lac operon encodes. Step 1: Recall the components of the lac operon. The lac operon consists of three structural genes: lacZ, lacY, and lacA. These genes are responsible for the metabolism of lactose. Step 2: Identify the function of the lacZ gene. The lacZ gene encodes the enzyme beta-galactosidase. This enzyme is crucial for breaking down lactose into glucose and galactose. Step 3: Evaluate the given options. (1) Repressor of the lac operon: This is encoded by the lacI gene, not lacZ*. (2) Transacetylase: This is encoded by the lacA* gene. (3) Permease: This is encoded by the lacY* gene. (4) बीटा-गैलेक्टोसिडेज (Beta-galactosidase): This is encoded by the lacZ* gene. The correct option is (4). The final answer is 4 Send me the next one 📸
