This is because eukaryotes have introns in their DNA as compared to prokaryotes. Therefore, after transcription, the pre-messenger-RNA has to undergo a process called splicing to form a mature mRNA that can be translated to a protein. This, therefore, gives the eukaryotes another window in which the regulation of the gene could be applied. Additionally, eukaryotes have a nucleus that separates the genetic material from the cytoplasm.Translation occurs in the cytoplasm while transcription in the nucleus. This separation gives the eukaryote the spacetime to regulate genes.
