2. Please fill in the information in the table below, telling if an E. coli bacterium that has the following genotypes will make a functional form of beta-galactosidase and/or permease in the presence versus absence of lactose. If the bacterium will produce a functional version of the protein, indicate this with a plus sign ("+"). If it will not produce the protein, indicate this with a minus sign ("-"). Assume all Z mutations are missense mutations that result in a nonfunctional version of the protein being made unless otherwise specified.
