< Completed out of 13 Resources Submit All 29 00 38 < Question 3 > Sucked A strain of E. colis genetically engineered in which the lacZ and lacl genes are removed and replaced with a gene encoding a fluorescent protein. A copy of the operon in which the protein product fluoresces green is inserted into the chromosome, and a copy in which the protein product fluoresces red is inserted into a plasmid. Both copies carry a wild-type laco gene, and the cells of the strain have a single copy of the lac repressor gene. If both fluorescent proteins are expressed, the cells fluoresce yellow because a combination of red and green fluorescence appears as yellow), and if neither of the fluorescent proteins is etpressed the cells show nofluorescence. the lacl pene in the genetically engineered fluorescent strain is mutated to an inactive form (lac!), the cells would in the presence of an indocer and in the absence of an inducer yellow.rod yellow yellow no fuscence, no florescence yellow, no florescence yellow, green
