I was just wondering if anyone out there knew anything about the lactose operon? We learned about it in Micro tonight and I don't fully grasp it. I know that (OR think I know that..) the promoter region initiates transcription and the repressor is the synthesis of mRNA...Im really unsure about the operating phase though. I also thinking Im leaving off a phase but I can't remember it! My proffessor said this was going to be on our test next week, and I want to know that I understand it!
