Identify the plasmid that must contain the cd3γ core promoter sequence but the fewest or

identify the plasmid that must contain the cd3γ core promoter sequence but the fewest or no negative regulatory sequences. based on the data in figure 2, describe the most likely cause of the variation in luciferase activity among the cells that contain plasmids pcd3γ-419, pcd3γ-309, pcd3γ-239, and pcd3γ-199. calculate the approximate percent increase in luciferase activity between cells containing plasmid pcd3γ-59 and cells containing plasmid pcd3γ-149. round to the nearest whole number.
