Which one of the following is the start codon?

Which one of the following is the start codon?

Options

  1. AAUG
  2. BUGA
  3. CUAA
  4. DUAG

Correct answer

A. AUG

Step-by-step solution

AUG is a start codon that codes for methionine whereas UGA, UAA and UAG are stop codons. The Initiator codon is the first codon of a messenger RNA or mRNA transcript translated by a ribosome. The start codon always codes for methionine in eukaryotes and a modified methionine, i.e., fMet in prokaryotes. Termination codons or stop codon is a nucleotide triplet within messenger RNA that signals translational termination.
