Question

One of the following is true with respect to $AUG$

• A. it codes for methionine only
• B. it is also an initiation codon
• C. it codes for methionine in both prokaryotes and eukaryotes
• D. all of the above

Answer 1

Answer: (D)

$AUG$ one of the codes in the genetic code is the initiation code which means that it is the first codon of a messenger $RNA$ $(mRNA)$ transcript translated by a ribosome. The start codon always codes for methionine an amino acid and is universal and codes for the same in both the prokaryotes and eukaryotes.
