Which of the following attributes is common to both prokaryotic cells and eukaryotic cells?

a. generally about the same size

b. the use of DNA as the information storage molecule

c. the use of proteins as information storage molecules

d. a membrane-enclosed nucleus membrane-enclosed organelles

b. the use of DNA as the information storage molecule

Explanation:

Prokaryotic cells are the ones that lack the membrane-bound organelles and well-defined nucleus. Eukaryotic cells have the nucleus and other membrane-bound organelles. Most of the prokaryotic cells are smaller in size as compared to eukaryotic cells. Despite these differences, both prokaryotic and eukaryotic cells have DNA as their genetic material. DNA serves to store genetic information in both types of cells.
