The amino acids specified by each codon are given in their three-letter abbreviation. The codons are written 5'-3', as they appear in the mRNA. AUG is an initiation (start) codon as well as the codon for methionine; UAA, 15.11 W anticodo Pairing at Watson-a are relaxe can pair UAG, and UGA are termination (stop) codons.Explanation / Answer
