Why are transcription and translation coupled in bacteria, but not in eukaryotes?

0 votes

 

In bacteria, both transcription and translation occur within the nucleus, whereas transcription and translation are uncoupled in eukaryotes since both occur in the cytoplasm.

Bacteria have only one polymerase that is responsible for both transcription and translation, whereas eukaryotes have separate DNA and RNA polymerases.

Eukaryotic transcripts are inherently less stable than prokaryotes, so they must be transported immediately to a ribosome to be translated.

Bacteria lack a nucleus, so transcripts are often translated before the transcript is even complete.
