Question
What is the function of the promoter in the E. coli lac operon? The promoter is a region of DNA at the start of the lac operon, where RNA p binds to begin transcription of the lactose genes. The promoter is a region of DNA outside of the lac operon that expresses a protein that inactivates the transcription of the lactose genes The promoter is a protein that prevents the transcription of the lactose genes by binding to the beginning of the lac operon. The promoter is a region of DNA at the start of the lac operon that switches lactose gene expression on or off through protein binding.Explanation / Answer
ques--
