Which of the following statements about the Lac operon is correct? Group of answer choices The Lac promoter is weak because its sequence deviates significantly from the consensus sequence. The Lac promoter is weak because it requires cAMP for transcription. The Lac promoter is strong because its sequence does not deviate greatly from the consensus sequence. The Lac promoter is strong so it requires a repressor for negative control.
