So we see that the RNA polymerase travels very quickly along our DNA molecule until it locates these promoted regions at which it binds onto the promoter region and it begins the process of transcription. It transcribes that bacterial cell and it uses the DNA molecule that is complementary to this DNA molecule that is shown here. Now, the question is, how does it know when to stop that transcription process? Well, in the same exact way that we have these promoter sections that initiate the process of transcription, we also have these termination sections, termination sites or termination sequences that essentially terminate or end the process of transcription. So essentially, the RNA polymerase will continue transcribing until it reaches a termination sequence. So in this particular diagram, this is our gene and this is our termination sequence.
