Question

Suppose a scientist generates random mutations in E. Coli and picks four strains to study. the scientist measures the protein level of B-galactosidase for each strain in the presence of different carbon sources, as show in the table below Question Question 8 of 24 Incorrect suppose a scientist generates random mutations in E. coli four strains to study.The scientist shown in the level of Bgalactosidase and picks of different carbon sources, as the table below. for each strain in presence Strain Lactose Glycerol Lactose and glucose 0 1 Wild type 100 100 1 Mutant 1 100 1 Mutant 2 100 100 Mutant 3 0 Mutant 4 1 Match each type of mutation to the corresponding data.
