A scientist records features of two cell samples.
| Feature | Sample P | Sample Q |
|---|---|---|
| Cytoplasm, cell membrane and ribosomes | Present | Present |
| Location of genetic material | Free in the cytoplasm | Enclosed inside a nucleus |
Which interpretation of the comparison is correct?
Both samples are eukaryotic, because both contain genetic material and ribosomes.
Sample P is prokaryotic and sample Q is eukaryotic, because only the genetic material in sample Q is enclosed in a nucleus.
Sample P is eukaryotic and sample Q is prokaryotic, because free genetic material identifies a eukaryotic cell.
Both samples are prokaryotic, because both have cytoplasm, a cell membrane and ribosomes.
