What is meant by the term coupled transcription/translation?

What is meant by the term coupled transcription/translation?



Translation begins before transcription has been completed
This only occurs in prokaryotes since they do not contain a nucleus
In eukaryotes, transcription is completed in the nucleus before translation can take place in the cytoplasm
