What is the sequence of prokaryotic protein expression?
Promoter recognition → transcription → translation → polypeptide formation → protein folding or processing.
What is the sequence of eukaryotic protein expression?
Transcription initiation → pre-mRNA production → RNA processing → export → translation → protein folding or modification.
Which cells normally perform extensive pre-mRNA processing?
Eukaryotic cells.
Why can bacterial protein production begin quickly?
Transcription and translation can occur simultaneously.
Are newly translated polypeptides always immediately functional?
No. Folding, assembly, or additional modifications may be required.
