Which of the differences are TRUE between prokaryotic and eukaryotic cells?

• in prokaryotic cells, DNA lies freely in mesosome while in eukaryotic cells, DNA located in the nucleus.

• Prokaryotic cells are generally larger in size (10 – 100 µm) while eukaryotic cells are generally smaller in size (0.5 – 10 µm).
