In this video, we're going to talk about the 3rd and final step of transcription, which is the termination of transcription. Termination is just a word that's referring to putting something to an end. The termination of transcription is the process that results in the end of transcription to produce an RNA molecule. It turns out that prokaryotes and eukaryotes actually differ in the way they terminate transcription. Specifically, in eukaryotes, eukaryotic termination forms a premature RNA molecule. This premature RNA molecule is not the final molecule in eukaryotic organisms. The premature RNA molecule in eukaryotic organisms requires further modification through RNA processing, which we'll get to talk more about as we move forward in our course. However, in prokaryotes, the RNA molecule that's formed is not a premature RNA, and it does not require RNA processing. The premature RNA is only going to be found in eukaryotic organisms.
If we take a look at our image down below at the termination of transcription, what you'll notice is that the RNA polymerase is reaching this terminator sequence here, and the terminator sequence on the DNA is going to initiate the process of termination. Ultimately, termination results in the RNA polymerase being released, and the RNA molecule being released. Now, again, in prokaryotic organisms, the RNA molecule is ready for translation immediately. However, in eukaryotic organisms, the RNA is a premature RNA, a pre-mRNA. This is not going to be the final version of the RNA in eukaryotic organisms. This RNA would have to undergo RNA processing in eukaryotic organisms before translation can take place. Again, this is only going to be applicable for eukaryotes, not for prokaryotes.
This here concludes our brief introduction to the termination of transcription, and we'll be able to get some practice applying these concepts as we move forward in our course. So I'll see you all in our next video.
