* Translation of languages: This process has no fixed end point. It's an ongoing activity with constant demand as languages evolve and new content needs to be translated.
* Translation in biology (protein synthesis): This process ends when the ribosome reaches a stop codon on the mRNA molecule. This signals the end of the protein chain and the ribosome detaches from the mRNA.
* Translation in other fields: For example, "translation" in music refers to the process of adapting a piece of music for a different instrument or ensemble. This process ends when the composer or arranger is satisfied with the result.
Please clarify what you mean by "translation" so I can give you a more specific answer.
