Now, when it comes to naming nucleotides, we're gonna say it's the name of the nitrogenous base with a suffix modifier. And remember when it comes to our nitrogen in spaces, we put them in two categories, our Pym which is our single ringed molecule and then our purines, which is our double ringed molecule. When it comes to pyrimidines, the ending changes to iodine and when it becomes purines, when it's involved, purines, it's all sign. If we take a look here, we have an RN A nucleus side being created. Remember RN A uses the nitrogenous space uracil. So here we have our ribo sugar. We have our uracil. When they connect together to a condensation reaction, we have the loss of water. This helps to create this glyco bond right here between the nitrogen and the atomic carbon. Here, we would change the ending of the nitrogenous space. So now it's no longer uracil, it's UDY. So we have replaced the AY or your cell part of this with iodine. Over here, we have the DNA nucleoside. So remember DNA uses two deoxy ribo sugar instead of ribo sugar like RN A. Here we have a nine again, we're going to have the creation of our glyco cytic bond right here between the nitrogen and the anomic carbon. Here. What we need to note is in addition to the suffix modifier, we have to use the prefix Deoxy to designate that this carbon number two doesn't have an oh, here it has just an H. So here the name would be Deoxy and because it is a purine ring, the ending is O sign. So it becomes a dental sign. So here I kept this part here and the iron portion became O sign. So two or so becomes the oxy a dental sign as the name of this particular nucleo sign. So just remember these naming conventions when it comes to our different types of N signs.

Now remember that a nucleotide is just a precursor to a nucleotide. We learned that when it comes to nucleotides, the pyrimidine, we change the ending to iodine. And with the purine, we change the ending to oide. Here, we're now looking at nucleotides with nucleotides, we would just add five prime mono monophosphate to the end of the nucleotide name. So just remember if we're looking at just the nucleoside portion, it would have been uh UDY. But because we're adding the phosphate group to make a nucleotide, we add five monophosphate five because the phosphate is connecting to carbon five prime. Over here, we had deoxy adenosine because it was a deoxy ribo sugar with our adenine or a nine nitrogenous space that gave us this deoxy adenosine as the name. But because we're adding this phosphate group to our five prime carbon, we add five prime monophosphate to the end of the name. So just remember to be able to name these nucleotides. It's important to remember the naming conventions and rules for naming the given nucleoside. Once you know the name of the nucleotide, just add five monophosphate to the end of the name

Here, we're gonna take a look at our naming summary. So we have our RN A and our DNA, remember the difference in bases is that for RN A, we use your cell and for DNA, we use thymine. Now, here with the nucleus side, remember when it comes to a pyrimidine, we change the ending to iodine. And when it's a purine involved as a nitrogenous base, the ending changes to OS sign. So if we take a look here, we have cytosine, uracil, adenine and guanine and then their nucleo side names for the pyrimidines, we change them to iodine. So cy Cyta iine uridine and then for the pur, we change them to sign. So adenosine guanosine with the nucleotide. All we do is we add five prime monophosphate to the end of name. So it'd be each of these with five prime monophosphate to the end of the name. Remember each one of these nitrogenous bases has a one letter code for themselves. So, cytosine is C, your cell is U A. It means a waning is G, but here we're talking about the monophosphate version of them. So we'd have to add MP at the end for monophosphate. So these would be their abbreviations with DNA. We have here, cytosine, thymine, adenine and guanine or remember with DNA, we have to use a prefix of Deoxy as well. So that's the, that's the difference here. We have Deoxy. But then the rest of the name is the same here. We have thymine and because thymine is a pyrimidine, it uses the ending iodine again, we have deoxy and deoxy just like RN A. Once we introduce the phosphate group to the five prime carbon, we add five prime monophosphate to the end of the name here. The difference. Now, in addition to these small changes like the oxy, we'd have to add ad lowercase D to the front of the name to represent the deoxy component in vault. Then we would include the one letter abbreviation for each of these nitrogenous bases. So cytosine is C thymine is T, adding is a, one is G and we're talking about the monophosphate version of them, the nucleotide version. So we'd write MP Fen. So these will represent the abbreviations of each one of these nucleotides. So just remember the naming conventions that you learn when it comes to nucleo sides and then when it comes to nucleotides, you add five prime model phosphate to the name. Remember the one letter code for each of these nitrogenous bases. We add MP to the end of it to represent the monophosphate. If a deoxyribonucleic acid is being used in the form of DNA, we add a lowercase D to the front of the name, right? So just remember these naming conventions and these naming summaries.

Here, it says name the following N sign. All right. So if we take a look at this image, we would see that in carbon number two, there's the absence of an oh group, just an eight year. So this means that we're dealing with DNA, with DNA. We have the prefix of Deoxy. Next, they tell me. So we're gonna say this is our prefixed the oxy. Next, we're gonna say we're dealing with a one ring, nitrogenous space, right? So that means that we're dealing with a perimeter. And if we're dealing with the perimeter, that means the suffix, the ending would have to be I die. And now what we need to do is we need to figure out what is our nitrogenous space. If we take a look here, this looks like the beginnings or the, the, the base form of uracil, except we've added a methyl group here, methyl group math group. So if we remember our different memory tools, meth, thy means that we're dealing with thyme. So the base here is thyme. So putting it all together Deoxy would be the beginning of the name. Remember the basis thy mean, but we're gonna change the ending to I don. So the base would be five and we get rid of the I and E part, we replace it with iodine. So the oxy thymidine will be the name of the given N side presented within this example question.
