E. coli can synthesize the amino acid threonine or absorb it from the environment. In the thr operon, the repressor is active when it is bound to threonine. If an E. coli bacterium is in an environment where threonine is absent, will transcription of threonine synthesis genes take place? Why or why not?
◦ no, because threonine will not be bound to the repressor, so the repressor will be inactive
◦ no, because threonine will not be bound to the repressor, so the repressor will be active
◦ yes, because threonine will not be bound to the repressor, so the repressor will be inactive
◦ yes, because threonine will not be bound to the repressor, so the repressor will be active
