Final answer:
Prokaryotic gene regulation is simpler than eukaryotic gene regulation. Eukaryotic gene expression is more complex because of the separation between transcription and translation, and the ability to regulate gene expression at multiple levels.
Step-by-step explanation:
Transcription is regulated differently in prokaryotes and eukaryotes. In general, prokaryotic regulation is simpler than eukaryotic regulation.
Eukaryotic gene expression is more complex than prokaryotic gene expression because the processes of transcription and translation are physically separated. Eukaryotic cells can regulate gene expression at multiple levels, including epigenetic, transcriptional, and translational regulation.
