Original Khojo Papers practice question — not from a past board paper.
Answer
A prokaryotic cell has no nuclear membrane, so its genetic material lies free in the cytoplasm; a eukaryotic cell has a true nucleus. A prokaryotic cell has no membrane-bound organelles; a eukaryotic cell has them. Prokaryotic ribosomes are 70S and eukaryotic ones 80S. Prokaryotic DNA is a single circular molecule; eukaryotic DNA is linear and associated with histones.
No citable source has been recorded for this record. Treat it as practice material, not as fact.

Bacteria and cyanobacteria are prokaryotic; all other organisms are eukaryotic.
