Answer question 1

Assume a bacterial cell has a mutation in the gene that codes for CRP, such
that the mutant CRP-CAMP cannot bind to the Lac operator. Which of the
following statements would be true in the event of such a mutation?
Transcription levels would be low when glucose levels are low and lactose levels are
high
All of the options are correct (i.e., all are true)
Transcription levels would be low when both glucose levels and lactose levels are
high
Transcription levels would be low when glucose levels are high and lactose levels are
low
Transcription levels would be low when both glucose and lactose levels are low
