The one which is present in all living things
Correct answer: B. DNA or RNA
- A. Cell nucleus
- B. DNA or RNA
- C. Cell membrane
- D. Vacuole
Explanation
All cellular living organisms contain genetic material, with DNA serving as the hereditary material and RNA functioning in gene expression; the phrase DNA or RNA also covers the genetic-material distinction used for biological systems. Students may choose cell membrane because cells require a boundary, but the wording includes all living things and does not state that every living structure must have a membrane as its defining common feature.
