Which structure would you not find in a prokaryotic cell?

Nucleus

Explanation:

The prokaryotic cells are very simple and their dispersed genetic material is the result of the lack of a membrane called the library, which delimits the nucleus in other cells, that is, the prokaryotic cells have no nucleus. In addition to the lack of library, prokaryotic cells do not have membranous cell organelles such as mitochondria, plastids, endoplasmic reticulum and golgiense complex. Importantly, they have ribosomes, and they are much smaller than those found in other cells.
