Accepted Answer

All right. Hello everyone. So this question is asking us to give the three letter abbreviations of the amino acid sequence for the given MRN a sequence labeled from five prime to three prime. So before we go ahead and start going through the answer to the question, let me just go ahead and rewrite the Mrna sequence given. So from five prime to three prime, we have GU CG A UUC U AC and AC C. So here we can see that these nucleotides, these MRN A nucleotides have been arranged into these three nucleotide units. These three nucleotide units if you recall are known as codons, right? And so each coon is going to code for one amino acid or it acts as a start or stop signal for translation. So translation, if you recall is the process of converting an MRN A template like the one that we're given into an amino acid sequence. Once the amino acid sequence finishes its folding, it becomes a protein. And the good news is that you don't have to memorize all of the codons. You might have to memorize the start and stop codons but not the ones that code for amino acids. So to understand what amino acids result from each co on, we would need to reference the genetic code. The genetic code being the table that has all possible coons listed as well as their resulting amino acid or once again, if that particular coon is a start or stop sign. So here let's go one by one and figure out which amino acid results from each coda. And because we're working with the three letter abbreviations for each amino acid, these abbreviations should be separated with a dash in between them. So first, let's start with GU again, going back to our genetic code and matching this particular code on to where it is in the chart. We would notice that GU codes for veiling and the three letter abbreviation of vain is simply its first three letters VA L. And this rule generally tends to be the same for all amino acids. There are exceptions, of course, but generally speaking, the three letter abbreviation of an amino acid is usually the first three letters. But again, there are exceptions. So the first is Vain and VA L and our next code on here is CG A. Going back to our genetic code. We noticed that CG codes for Argen and the three letter code for Arginine is A RG. So once again, it's first three letters from there, we have UU which according to our table gives us pheno Alanine. So that's going to be Phe second to last code on is U AC which codes for tyrosine. So that's Tyr and our very last code on is AC C which codes for three and E. So that's T hr So there you have it, our amino acid sequence from five prime to three prime is vine arginine, phenylalanine, tyrosine and three anine. And it just so happens that all of these amino acids use their first three letters as their three letter abbreviations. And so with that being said, thank you so very much for watching and I hope you found this helpful.
