Review Figure 19.15 below: Which one of the following statements about the lactose operon is not correct?
A. The lacZ coding sequence for - galactosidase and lacY coding sequence for lactose permease are genes called structural genes. B. lacO is a gene sequence coding for the operator. C. The promoter sequence recruits RNA polymerase complex and the initiation of transcription. D. lacI is a gene sequence coding for the repressor which binds to the operator, inhibiting transcription.
