You have been tinkering with E coli in your lab and decided to remove the lacy gene from the loc operon and put it back in the genome somewhere else. Briefly, what would be the result if you replaced the missing lace gene by inserting it into the following locations: a. Under control of the laci promoter, as a polycistron with the lacl gene? b. Under control of the laci promoter, as a knock-in replacing the lach gene? C. As part of the rof operon polycistron, which is an operon responsible for breaking down the sugar rubiose?
