| DNA organisation | A prokaryotic chromosome consists mainly of a circular DNA molecule associated with a few proteins. | A eukaryotic chromosome contains a large DNA molecule packaged with many proteins, including histones. |
| Location | A prokaryotic chromosome is located in the nucleoid region, which is not enclosed by a nuclear membrane. | Eukaryotic chromosomes are located inside a membrane-bound nucleus. |
| Packaging | A prokaryotic chromosome is organised into large loops held by proteins. | Eukaryotic DNA is packaged into nucleosomes, chromatin and condensed chromosomes. |
