Trna is used in translation or transcription ?

Translation.

Explanation:

The mRNA formed in the transcription process is transported out of the nucleus, then goes into the cytoplasm, and then to the ribosome. The ribosome is called the cell's protein synthesis factory.

In the ribosome, it directs protein synthesis. Messenger RNA is not directly involved in protein synthesis. Transfer RNA (tRNA) is required for this. The process by which mRNA leads to protein synthesis with the assistance of tRNA is called translation.

So we can say that the transfer RNA (tRNA) is used in the translation process.
