Which structure is found in the cytoplasm of a prokaryotic cell, but is not found in the cytoplasm of a eukaryotic cell?

Prokaryotic cells have no nucleus, so their DNA is located in the cytoplasm, in a region called the nucleoid. In eukaryotic cells, most DNA is enclosed in the nucleus rather than freely located in the cytoplasm. Ribosomes occur in the cytoplasm of both cell types.
