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
