Prokaryotic and eukaryotic cells generally have which of the following structures in common?
A. a membrane-bound nucleus
B. a cell wall made of cellulose
C. ribosomes
D. linear chromosomes made of DNA
Choose A, B, C or D as your solution.
The correct answer is C. Prokaryotic cells lack membrane-bound organelles including a nucleus. Their DNA is circular and does not exist as linear chromosomes. Prokaryotic cells can have a cell wall, but it is typically made of peptidoglycan. The only item on this list that is common between prokaryotic and eukaryotic cells is that they both contain ribosomes needed for protein synthesis within the cell.
