Reseаrchers discоvered thаt а new strain оf bacteria that causes tuberculоsis (M. tuberculosis) has a point mutation in the rpoB gene that codes for part of the RNA polymerase enzyme. This mutant form of RNA polymerase does not function as well as the more common form of RNA polymerase. A commonly used antibiotic called rifampin does not affect the mutant rpoB bacteria.A researcher creates a population of M. tuberculosis with and without the rpoB mutation. She then adds individuals from this mixed population to cell cultures. Half the cell cultures contain only standard nutrients, while the other half of the cell cultures contain rifampin and the standard nutrients. (You might find it helpful to sketch out this experimental setup on your scratch paper). After many generations, you might expect the researcher to find________.
