Unlike in eukaryotic cells, in prokaryotic cells, once the protein is synthesized following translation, that protein is not modified in any way. But in many eukaryotic cells, many eukaryotic proteins are actually modified in different ways in the Golgi apparatus following translation. And so what that means is we can add different types of components onto our protein, for example, sugar molecules and lipid molecules. We can also cleave proteins in eukaryotic cells post translationally. And these things cannot be done inside prokaryotic cells. So prokaryotic cells simply don't have the machinery, they don't have the Golgi apparatus and other organelles to basically modify the proteins posttranslationally.
