Translation: Initiation, Elongation, Termination · Zoology

Termination of translation occurs when the ribosome encounters:

  1. A start codon (AUG)
  2. A sense codon for an amino acid
  3. A stop codon (UAA, UAG, or UGA)
  4. A Shine-Dalgarno sequence
Show answer and explanation

Correct answer: A stop codon (UAA, UAG, or UGA)

Stop codons (UAA, UAG, and UGA) signal the end of translation. They are not recognized by any tRNA and do not code for an amino acid; instead, release factors bind and trigger polypeptide release.
