the answer I gave was wrong
Which of the following statements about gene regulation concerning operons is INCORRECT? A regulator gene has its own promoter and is transcribed into an independent mRNA. For an operon under negative repressible control, a correpressor is required for the repressor to bind to the operator. Presence of operons where genes of related functions are clustered is common in bacteria but not in eukaryotes. For a gene under positive repressible control, the normal state is...
