Answer & Solution
Correct answer: D. A nucleus
1. All cells share a plasma membrane, cytoplasm, DNA, and ribosomes.
2. What a prokaryote lacks is a nucleus, or any other membrane-bound organelle.
3. Its DNA still exists; it simply sits in a central region called the nucleoid instead of inside a nucleus.
