All right. Hello everyone. So this question is asking us which of the following abbreviated names of nucleotides is incorrect. And here we have four different answer choices labeled A through D proposing different acronyms as well as different names for each nucleotide. So before we talk about these individual names, let's just talk about the conventions behind naming nucleotides. And very quickly just to go ahead and clarify, recall that a nucleotide is composed of three main parts, we have the nitrogenous base, the sugar backbone and a phosphate group or groups. So from there, let's talk about some naming conventions first in some of the answer choices, namely options, A and D, you'll notice that there is a lower case D as the first letter of the abbreviated name, right of the acronym. This is going to stand for D OXY. This indicates therefore that the sugar backbone of these particular nucleotides are deoxyribose instead of ribose. So the presence of deoxy rivals is characteristic of DNA. So if the lowercase D is not present, that means that the sugar backbone is simply ribose, which is characteristic of RN it. So from here, let's talk about the names of the nitrogenous basis. Now recall that the nitrogenous bases can be characterized in two different ways, right? There are two different categories. We have the purines that include adenine and guanine. And we also have the pyrimidines which include cytosine, thiamine and uracil. Now, the suffixes of each of these bases is going to change when representing them in the name of a nucleotide. But depending on which category they fall into that new suffix is going to be different. So for example, if the base in question of your nucleotide is a purine, then the new suffix is going to be O si ne. So we go from adenine, for example, to adenosine and guanine becomes guanosine. On the other hand, if the base of your nucleotide is a pyrimidine that is cytosine thymine or uracil, then the new suffix is going to be id ine oops. So for example, we would go from thymine to something like thymidine to reflect that new suffix. So last but not least there's one more component which is the phosphate group or groups plural, right? So the phosphate groups in a given nucleotide are represented by the capital peak representing phosphate in these abbreviations. Now, there should be another letter directly in front of the capital P to represent how many phosphate groups are in each nucleotide. So for example, we have monophosphate to represent only one phosphate group. So it's MP DP stands for diphosphate representing two phosphate groups and TP stands for triphosphate reflecting three phosphate groups. So these are the conventions that we should keep in mind when analyzing each name of the answer choices. So now let's focus on option A to start off. Option A is DGTP which is short for deoxy guanosine five prime triphosphate. This is correct, right? Because we have the capital D reflecting deoxyribose or excuse me, lowercase D, the name guanine has been changed to guanosine because our base is appearing and TP accurately states that we have three phosphate groups. So option A is correct. Moving on to option B. It says at P is adenosine five prime triphosphate. This is also true, right? Because this time there is no lower case D which means that it's not going to be deoxyribose, the A for adenine or rather adenine being the base here has been correctly changed to adenosine in the name of the nucleotide. And TP does stand for triphosphate. Moving on to option C. It says that DC MP is deoxy cytosine five prime monophosphate. So it is in fact deoxyribose, an MP does stand for monophosphate, but the name of the nitrogenous base has not been modified in the way that it should, right. Cytosine is a Peridin, which means that the suffix should have been changed to ID ine. Therefore, the correct name would have been deoxy cytidine monophosphate, not deoxy cytosine. So option C is incorrect, but for the sake of completeness, let's talk about option D it says UTP is uridine five prime triphosphate. This is correct, right. Our base here must be rivals Uracil as IL has had its suffix changed to urine and TP does stand for triphosphate. Therefore, our answer is going to be option C in the multiple choice. And with that being said, thank you so very much for watching and I hope you found this helpful.
