Detailed explanation-1: -This statement is false, AUG codes only for methionine amino acid. One codon codes for specific amino acids only but one amino acid can be coded by more than one codon.
Detailed explanation-2: -14.1 (POB) Methionine Has Only One Codon. Methionine is one of the two amino acids having only one codon. Yet the single codon for methionine can specify both the initiating residue and interior Met residues of polypeptides synthesized by E. coli.
Detailed explanation-3: -Most of the amino acids in the genetic code are encoded by at least two codons. In fact, methionine and tryptophan are the only amino acids specified by a single codon. Importantly, the reverse isn’t true: each codon specifies just one amino acid or stop signal.
Detailed explanation-4: -Methionine and Tryptophan are the amino acids that can be coded by a single codon triplet. The codon for Methionine is AUG.
Detailed explanation-5: -The codon AUG is called the START codon as it the first codon in the transcribed mRNA that undergoes translation. AUG is the most common START codon and it codes for the amino acid methionine (Met) in eukaryotes and formyl methionine (fMet) in prokaryotes.
