12. Gene Regulation in Prokaryotes
Lac Operon
12PRACTICE PROBLEM
Suppose you conduct a northern blot analysis using a probe specific to the lacY gene of lac⁻ bacteria with non-functional promoter and operator regions. What will you expect in the appearance of gel electrophoresis when you run an mRNA isolated after growth in a lactose-only medium?
