Final answer:
Termination of translation occurs when a stop codon is encountered. The growing polypeptide is released and the ribosome subunits dissociate and leave the mRNA. After translation is complete, the mRNA is degraded.
Step-by-step explanation:
Termination of translation occurs when a bered. When the ribosome encounters the stop codon, the growing polypeptide is released and the ribosome subunits dissociate and leave the mRNA. After many ribosomes have completed translation, the mRNA is degraded so the nucleotides can be reused in another transcription reaction.
