This separation of the DNA from the protein synthesis machinery provides eukaryotic cells with more intricate regulatory control over the production of proteins and their RNA intermediates. In contrast, the DNA of prokaryotic cells is distributed loosely around the cytoplasm, along with the protein synthesis machinery.
Proteins have many important roles in cell function like structural support, biocatalysts, receptors.
Answer:
If it helps, the answer is Mutualism (let me know if it is for some reason incorrect)
