State
Translation termination occurs when a stop codon reaches site A, where a release factor, not a tRNA, binds and frees the protein.
Show
A release factor recognizes stop codon UAA, UAG, or UGA at site A and triggers hydrolysis, releasing the finished polypeptide.
Watch for
No tRNA carries an anticodon matching a stop codon — a release factor's shape mimics tRNA closely enough to bind.
