The key to this theoretical question lies in some of the information you provided.
The first thing to consider is the differences between eukaryotic and prokaryotic transcription. So you suppose that prokaryotic promoter sequences and transcription enhancer sequences are the same as eukaryotes? Will prokaryotic transcription enzymes recognise eukaryotic promoter regions?
Equally, what about the differences in post transcription processing between eukaryotes and prokaryotes? Do prokaryotes and eukaryotes process RNA into mRNA the same way? What are the differences between splicing for example.
Think about these questions and you'll arrive at your answers!
