Accepted Answer

All right. Hello everyone. So this question is asking us if the sequence of the DNA template strand is GATCCG TA A GC, what would be the corresponding TNA anticodon? So this is a question that's not as straightforward as others that you may have come across, right? Because a very common type of question is forcing you to recall facts about the process known as transcription in which a DNA template strand is converted into or is used to create rather an MRN A molecule from there during a process known as translation, the MRN A molecule provides a blueprint, so to speak, that it will eventually result in a complete protein. But this question isn't asking you to produce the Mrna. Rather recall it during translation. Tr nice are molecules that bring amino acids to the ribosome to allow for the polypeptide chain to grow, right? It's bringing new amino acids to add to the growing polypeptide. And so the way in which a Trna molecule will recognize where to go is by binding with its an decoder. So just to backtrack here a little bit more when MRN A is synthesized, right? We can describe a group of three nucleotides as a coon. It's a specific grouping of three nucleotides that codes for one amino acid each. So three nucleotides codes for one amino acid. The anticodon is the sequence in the TRNA that is complementary to the coon of the MRNA that allows for the TRNA to recognize that sequence, that part of the strand and therefore add its amino acid to the chain. So first let's draw out the MRN A or find the coons rather. Now, the nice thing here is that the DNA template has already been grouped or has already been split off into groups of three. So the first is gat for a question like this, it's important to recall the base pairing rules. So here, because we're talking about MRN A, there is no thymine rather, there's only going to be il this means that Adenine binds with uracil and vice versa or pairs with uracil and guanine pairs with cytosine and vice versa. So using this rule, right, if the first set of nucleotides in the DNA template is G A. The first coon of the MRN A is going to be cug my bad, actually going to be C A. It's CU A because recall that thymine does bind with adenine, you're just not going to see it in MRN A thymine rabbit. So just to clarify, our first code on is cux. This leads us now to our second group of three nucleotides in the DNA template which is CCG. So the second code on is going to be GGC. Up. Next, our next grouping is TA A on the DNA strand, which means that our third coat on is A you, you. And last but not least our last grouping of three nucleotides is GGC, which means that our last code on is going to be CCG. And so from here, we can find the anticodon on the TRNA. Now, there are two ways of finding the anticodon, finding the Tr Nate or the sequence on the Tr Nate. What you could do, first of all is find the complement to each code on using the base pairing rules that we talked about earlier. However, another way is to recall a few relationships, right? First of all, the DNA strand is complementary to the Mrna strand and the MRN A strand is complementary to the TRN A strand. This means that you can find the anti codons by simply copying the DNA template. The only difference, however is that thymine has to be replaced with uracil because once again, this is RN A. So for example, I could use the base pairing rules with my M RNA strand as a template. But using this DNA sequence here, I can just say that Gau is going to be my first anticodon once again replacing thymine with yourself. And this is complementary to the coon same thing with the second that's going to be CCG. And then we have you a a and then we have GC and there you have it. Now we have our sequence of anti codons. And so with that being said, Nikki, so very much for watching. And I hope you found this helpful.
