True, they can have genetic differences.
Answer:
Option (3).
Explanation:
The process of the transcription and translation is quite different in case of prokaryotes and eukaryotes. Transcription and translation is couple together in prokaryotes whereas it takes place in separate compartment in case of eukaryotes.
The gene has been transferred from the eukaryotes to prokaryote but the protein produced is quite different. This might occur due to the presence of introns in the eukaryotes whereas prokaryotes do not have introns. In case of eukaryotes, the protein express after the splicing process but no splicing occurs in prokaryotes and give different product.
Thus, the correct answer is option (3).
