If the lacI gene in the genetically engineered fluorescent strain were nonmutant but the lacO sequence on the chromosome mutated to lacOc, how would the cells fluoresce in the presence of inducer? In the absence of inducer?

if the lacI gene, in the genetically engineered fluorescent strain were non-mutant but the lacO sequence on the chromosome  is mutated to lacOc then,

in the presence of the inducer, the cells fluorescence will show

yellow; red

in the absence of inducer, the cells fluorescence will show,

yellow; no fluorescence.

Explanation:

when lacO is mutated with lacOc then constitutive mutation happens which lets the system to be on.

answer; a muscle cell, another neuron and a of the above
