Question

Third-base wobble allows some tRNAs to recognize more than one mRNA codon. Based on this chapter's discussion of wobble, what is the minimal number of tRNA molecules necessary to recognize the following amino acids?

arginine

Hello, everyone and welcome to today's video. So besides the coon G G G, what is the other codon that can be recognized by the anti coon C C and C? So as answer choice A, we have a G C as answer choice BC G G as answer choice C G A G and as answer choice D G G C. So we have an anti code which is going to be C C and C. Now, this anti codon is going to perfectly recognize the coon G G G because it's complementary to it. However, we know that the genetic code is degenerate, meaning that the third position of this can be recognized by the same anti coon by the same T R N A even though we change it. So we could change this third position to quite clearly any other nucleotide such as G G A G G C and G G U. And we would still be able to recognize it using C C C is that we reduce the number of T R N A molecules that are necessary to create a protein because the genetic code, like we stated is generate. So looking at what we got here. The only one of these coons that are present in our answer choices is going to be this coom G G C which is going to be answer choice D G G C, I really hope this helped and I hope to see you on the next video.
