Identify the following amine bases found in nucleic acids:...

Name two nucleic acids found in organisms.

Question 66. Our topic is nucleic acids and what we need to d'oh! I said, Draw. The three perimeter eating bases has the following structure. It's a six member. It ring with two with four carbons and to NYU visions. So that's what permitting ring looks like in its most basic form. There are three bases that have this general structure our site is in. You convey this. I mean, it's our 2nd 1 and yourself. All right, let's draw. Side is seen first. Go ahead and draw our six member ID ring. Connect all these. There are two double bonds in the ring. One here, one there on this carbon. We have an amine group and each too. And on this carbon here we have a double bonded oxygen. Everywhere else, we fill in with hydrogen Sze to satisfy the octaves for the other Adams and, uh, in the ring. So happens that they each only need one except for this one. Actually, that one doesn't need to be there. Not generally usually only has three bonds. It's Nick most neutral form, so there's a structure for side a scene. Now let's draw fine mean there are six member and ring. This has one double bond in this ring right here on this carbon. We have definitely bonded oxygen. Same thing on this carbon. So got to Carbondale groups. And then on this carbon. Here we have a metal group ch three and then everywhere else we put our hydrogen Sze to satisfy the OC tents. So that's the structure for timing. Now let's draw yourself. There are six members. Bring Justus before we have one double bond. Here we have to doubly bonded Oxygen's. And instead of a metal group, we're just gonna have a hydrogen here. So the structure of your cell is basically the same Miss Fine mean, But without the metal group, we put our hydrogen sze where they need to go. And that's your cell. So these were the structures of all the perimeter ing basis found in nucleic acids. And they all have this this one ring feature in common. The six member ring

All right. So, problem 31 here, forgiven to bases and asked to named the ways and also figure out a foot scene in DNA or RNA or both. So the way we go about this is to just look at the, um, different function groups or different atoms that are connected to our kind of ah, main ring. Right? So started would part ay here. We see that, um, we got this group sticking out of our ring and everything else would just be hydrogen is right. The white spheres, some represent heart surgeons. So this is an N H two group. So whenever you only have n h two and nothing else, um, connected to the ring you got on adding right and also added, Dean would have this two rings connected to each other. That's also characteristic of both adenine and guanine, actually, So this n h do tells us it's ad Deen. So where do you see adding induce e it and DNA or RNA or both? And we know that the only difference between DNA and ornate is the you're selling timing so adenosine would be found in, but Okay, Okay. So, Part B, I'll be right here. We see that we got too hard A gin or sorry to oxygen. Adam's connected to our ring. So whenever you see to oxygen, um, Adam's connected as such immediately. We think either way I mean or yourself. Okay, so those are the only basis in the way or Arnie, that has that kind of structure. Hey, So what tells us whether it's you or you as whether we have this methanol group right here? So this is stage three. Okay, So if you have that ch three, that means you have a timing. So this the structure right here is a timing if you don't have that ch three than you have a years old. So where do you see I'm initiate your name, our name or both. And we know that I mean, could be found in DNA on Lee uni on Lee. Because in Orinda, we have yourself and not sight means. Okay, two, Those are our answers for this one.

Problem. 7 to 6. We are identifying amino acids. Okay, so we are given this massive molecule right here and were asked to identify amino acids. Okay, So what's nice about this molecule though it is, it's drawn in a way that we have our backbone and a straight line. Right. And everything outside this box would be our our escape. So those are our groups? No, that's gonna help us to identify our amino acids. And since we have six are groups, as you can count those blue circles meaning we have six amino acids. So I'll go and erase those blue circles to make it easier to see and to go for it. Okay. So first, our first group right here. Hey, we have a CH but we have a c connected to two more meth old groups. Okay? And if you notice it looks like a V, an upside down V. And that's how I remember the amino acid veiling. Okay, It looks like a V next. Next group. Right here. We have a c h 20 h. Okay, So I think this is just something you have to memorize. That would be Syrian. That would be serious. So you have one carbon and then it ends with a alcohol group. Okay. All right, then, um, our third. Our group here is very, very unique. It has that fennel group attached to it. So from fennel, it has a federal group that tells us this is fennel Valentin and it got stopped name because Alan in on Lee has th three, as in our group. And then you connected a benzene ring to it, or you connected a fennel group. So hence the name fennel. Alan. Hey. Next. Afford our group right here? As you can see, it has he has a sulfur. So meaning we could only have either Sistine or meth. I need Hey, but since since our s is in the middle of carbons, that means we have Bethany in. Okay, fine. If it was assisting, that s is gonna be the very end, Adam. Okay, so we're gonna have s h of little assistant. Next. We got this, our group, and you see that it has alcohol in it. Okay, So if you have an alcohol in your our group, you could either have Syrian or reuniting. Okay, So Syrian us, we already saw on this. Our group, it only has one carbon with it. Okay, So meaning this would be our three yearning three innings. And finally, here we have a very simple our group. It We just have a ch three, so that would be our elonis. So we have. We have six. We have six amino acids on this molecule. And, um, if it helps, let's go ahead and write it as one molecules. We have failing. We got Syrian, Got fennel, Ellen in. We got Miss Ayanami. We got three innings, and finally we have Ellen. So hopefully that was

So here we can just look or d and a basis. So we are five bases in total that I used to cross DNA on our on A So we have adenine, thiamine, cytosine, guanine in your PSA No. In de and a we have pardoning timing cytosine on Wanni so that present in d n a. The way in all and a we have added mean scientists ing warning and you're so the present in our and A now for our yourself places find me. So just to recap in DNA, we have adding finally cytosine guanine. However, in our and I assign me is not present and instead we have your so
