What by-product can be measured for in a cell if lacZ is being used as a reporter gene?

Question

Quizplus · Accepted Answer

LacZ is a gene that codes for beta-galactosidase, an enzyme that breaks down lactose into glucose and galactose. Therefore, measuring the activity of beta-galactosidase is a way to indirectly measure the presence of lactose as a by-product. Choice C lists "beta-galactosidase" as an option, and correctly labels the enzyme as "F1F1F1S1F1F1F10-galactosidase." The other options listed are for other reporter genes and their by-products, and are not directly related to lactose metabolism.
