Question

Transcription and translation are typically coupled in prokaryotes. Explain what this means. Why is this possible in prokaryotes and not eukaryotes?

Answer 1

mRNA processing is the only factor which is responsible for this difference

In eukaryote mRNA is processed i.e. introns are removed , 5' cap is added 3' poly -A is added.

so both process can not be coupled in eukaryote......

Answer 2

the main reason is that in eukaryotes you have the nucleus... transcription is there. translation mostly in the cytoplasm. prokaryotes dont have compartmetnalization, thus can couple translation and transcription

Answer 3

That is not proper reason

I can bet on it

If eukaryote cell use RNA directly without processing then it will able to translate it.
mRNA recognition is based on 5' cap in eukaryote

Answer 4

here coupled means both translation and transcription occur at same time in prokaryotes.
it dosent happen in prokaryotes as adesh said this is the accurate reason but yes another reason is also dat ttom said becoz eukaryotes are more complex than prokaryotes
