The three structures found in both prokaryotic and eukaryotic cells are:
ribosomes, DNA, cytoplasm.
- Ribosomes are the sites of protein synthesis and are present in both types of cells.
- DNA carries the genetic information and is found in both prokaryotic (as a single circular molecule) and eukaryotic (packaged in the nucleus) cells.
- Cytoplasm is the gel-like substance within the cell membrane where various cellular components are located, and it is present in both cell types.
The other options either include structures not found in prokaryotic cells (like mitochondria and nuclei) or structures that are specific to plant cells (chloroplasts).
