Title: What are the amino acid sequences coded for by each mRNA? Post by: rjandmj82 on Sep 14, 2012 i dont understand this last part of my homework. Can anyone tell me the answer or tell me how to do it? I have the three anticodons for mRNA. Here they are:
#1 AUCCGGUAGCCUUAGUUUAC #2AUGCCCCCGAUUCUCUUGA #3AUGGACAAUUCGAUGUUUUAA any help is much appreciated! Title: What are the amino acid sequences coded for by each mRNA? Post by: MightofMjolni on Sep 14, 2012 U is correspondant to A and A is correspondant to U.
G is correspondant to C and C is correspondant to G. You are looking for the opposite nucleotide (A/U/C/G) for each of the three problems. So, first one: UAGGCCAUCGGAAUCAAAUG Try the other two on your own :) Title: What are the amino acid sequences coded for by each mRNA? Post by: julie7 on Sep 14, 2012 Content hidden
Title: What are the amino acid sequences coded for by each mRNA? Post by: tommychk0235 on Sep 14, 2012 These are the codons of mRNA and you have to find the amino acids coded by them. This will help you.

Codons are read in 3's, so for #1: AUC, CGG, UAG, CCU, UAG, UUU, AC AUC is isoleucine CGG is arginine UAG is actually a STOP codon, so this terminates the sequence so #1 is isoleucine-arginine #2 AUG is methionine, which is the important start codon, necessary for most protein synthesis to begin, so #1 above probably wouldnt make any protein, as it has no start codon, even though it does technically code for amino acids. so just continue #2, next is CCC = proline, CCG = proline, AUU isoleucine, all the way down. Usually you need sets of 3's, and in #1 you end with AC and #2 just has A, so idk what to tell you about that part |
