 The second part here though is that we're going to need to take DNA and turn it into RNA and that's a process called transcription. I know that there are many concepts here but the way I remember this is that DNA is letters, right? It's typing. RNA is also letters typing. It's just a different type of letters and if I'm changing a type of alphabet to another alphabet I'm literally transcribing something. I'm changing how it's written. So I'll draw this two arrows because there's a first step here that corresponds to transcription. Transcription does pretty much exactly what we did on the DNA but for RNA. So there is a molecule here called RNA polymerase that was discovered by Roger Kornberg and it got the Nobel Prize for this in 2006. It's a very cool protein and that is the one that creates this messenger RNA molecule that will then be sent on to the ribosome to build the actual proteins.
