And so now we form that RNA molecule. And that RNA molecule can be modified in different ways if it is found inside eukaryotic cells. Now, another way by which we can terminate the process of transcription is by using a special protein known as row. And we'll discuss what the mechanism of this protein is in a future lecture. So the important point about this lecture is there are these promoter sites and these termination sites which basically work with that RNA polymerase and allow that RNA polymerase to basically transcribe that gene of interest. It allows these promoter sites, allows the RNA polymerase to locate and detect where that gene is.
