Which set lists the four components shared by all cells?

ANucleus, cytoplasm, DNA, ribosomes
BPlasma membrane, cell wall, DNA, capsule
CPlasma membrane, cytoplasm, DNA, ribosomes
DNuclear envelope, cytosol, DNA, flagella
Answer & Solution
Correct answer: C. Plasma membrane, cytoplasm, DNA, ribosomes
1. Every cell carries a plasma membrane that separates its interior from the surrounding environment. 2. Every cell carries cytoplasm, a jelly-like cytosol holding the other cellular components. 3. Every cell carries DNA as its genetic material and ribosomes that synthesize proteins. 4. A nucleus is absent from prokaryotes, and cell walls and capsules are absent from animal cells, so neither can be universal. 5. The four shared components are plasma membrane, cytoplasm, DNA and ribosomes. _Source: OpenStax Biology (1st ed., CC BY 4.0), Ch 4 "Cell Structure", section 4.2 Prokaryotic Cells_
