 I'd like you to meet my friend, the tRNA molecule. Once again, this is what it actually looks like. And it is made out of RNA nucleotides, and you can see that it actually forms a double-stranded kind of double ladder in some places on this molecule. So that's one of the reasons why it becomes misleading to say that RNA is always single-stranded, because it can actually fold and stick to itself. It does have this kind of clovery shape, or kind of an L shape if you lose track of your clovers. And there are two places on a tRNA molecule that are really significant. And so now we're going to go to Wendyland and I'll show you what they look like. Scoot over RoboZone because we got to talk about the tRNA. First of all, it looks like, remember that basically, and it has this place right here, which how am I going to draw this? This is like a sticky magnet. It's like a sticky magnet thing. Guess what's going to go on there? To my sticky magnet thing. It's an amino acid. Remember, what is this thing? It's a tRNA. That's awesome. Guess what else a tRNA has? Seriously. Now, this is a wind-ified version, of course. Would I just draw you dogs? I drew you three bases. I'll just make up some letters. U, G is called an anticodon. Okay, just take a second. Take a second and breathe about how amazing this is. You have codons in your messenger RNA, which is just three bases. If you match the codon with the anticodon on a tRNA molecule, do you agree that I'm going to bring a specific amino acid into the mix? I know your mind just blew, so do mine. Even though I've done this like a million times, it's just so cool. Okay, now it's time for an animation where we can actually see this whole thing unfold before your very eyes.
