All right. Hello everyone. So this question is asking us to predict the amino acid that is encoded by the code on option A says Lucine B says Glycine C says tryptophan and D says arginine. So recall first and foremost that a coon right refers to a nucleotide triplet and to be more precise, this is a nucleotide triplet found in Mrna. So each individual coon found within MRN A is going to be converted into either an amino acid or a start or stop signal during the process of translation translation being the conversion of the MRN A into an amino acid sequence and eventually a protein after it undergoes folding. So the good news is that you don't have to memorize all of the coons, maybe you might have to know the start and stop codons but not the ones for amino acids. So to get an answer to a question like this, you would reference a table known as a genetic coat. And so the genetic code is basically a table listing each possible code on right and matching each codon to its respective amino acid or again start stop codon. So before we go ahead and talk about what the answer is for this particular coon recall that each coon is going to result in one amino acid, but multiple amino acids or rather multiple codons can code for one amino acid. So with that being said, right, we move on now to our given which is GGU. So now referencing the genetic code table, you would find G in the first column or G as the first letter G as the second and U as the third. And so that according to the genetic code would result in glycine. So there you have it, our answer is going to be option B because our given code on codes for glycine. And with that being said, thank you so very much for watching. And I hope you found this helpful.
