• Question 70:

  Prokaryotic and eukaryotic cells are similar in having which of the following?

  A. Presence of a nucleus

  B. Protein-studded DNA

  C. Integral membrane proteins in the plasma membrane

  D. Membrane-bound organelles

  Correct Answer: D

  Both prokaryotes and eukaryotes interact with the extracellular environment and use membrane-bound or membrane-associated proteins to achieve this. They both use diffusion and active transport to move materials in and out of their cells. Prokaryotes have very few proteins associated with their DNA, whereas eukaryotes' DNA is richly studded with proteins. Both types of living things can have flagella, although with different structural characteristics in the two groups. The most important differences between prokaryotes and eukaryotes are the lack of a nucleus and membrane-bound organelles in prokaryotes.
