Bacterial and eukaryotic cells primarily control gene expression at the level of transcription. if instead cells exerted control of gene expression primarily at the post-translational level, what would be different?

At post translational level of gene expression prokaryotic protein is less modified than that of eukayotes .

Explanation:

Post translational modification is less affecttive in case of prokaryotes than that of Eukaryotic  protein .

                        There are more covalent modification of proteins in eukaytotes than that of eukaryotes .The covalent modification that occur in eukaryotic protein such as  Acetylation,phosphorylation,dephosphorylation,hydroxylation,ubiquitination.

   On the other hand protein phosphorylation is the most evident post translational modification in Prokaryotes .

  Very low  degree of glycosylation occur in prokaryotic protein in comparison to that of Eukaryotic protein.

      Palmitoylation of cystein residue of protein occur in eukaryotes but do not occur in case of prokaryotic protein.
