After the initial Actualization of the Cit+ phenotype, there was another alteration to the A-3 genome that resulted in increased growth (e.g. Refinement). What explained the increase in growth rate in response to Refinement? A. Increase number of transporters localized to the plasma membrane. B. Increased ability to metabolize glucose. C. Increased citric acid cycle activity. D. Altered promoter activity resulting in constitutive gene expression.
