Which statement accurately describes Eukaryotes?

• A. They have DNA inside a nucleus and membrane-bound organelles
• B. They lack a nucleus and membrane-bound organelles
• C. They are always multicellular
• D. They have no DNA

Answer: (A)

The main idea here is that eukaryotic cells are organized with a nucleus and membrane-bound organelles, which compartments the cell’s DNA and its metabolic processes. This internal organization is what sets eukaryotes apart from prokaryotes, which lack a nucleus and most membrane-bound organelles. The statement captures this defining feature: DNA is inside a nucleus, and the cell contains membrane-bound organelles that create separate compartments for different functions, like energy production and protein processing.

This helps explain why the other ideas aren’t correct: some cells in question have no nucleus or membrane-bound organelles, which describes prokaryotes; eukaryotes are not limited to multicellular organisms since many are single-celled; and eukaryotes do contain DNA, just as prokaryotes do.
