Nucleic acids were named so due to:
Correct answer: D. Their isolation from nucleus and acidic nature
- A. Their isolation from nuclei
- B. Their isolation from pus cells
- C. Their acidic nature
- D. Their isolation from nucleus and acidic nature
Explanation
The term 'nucleic acids' originates from their initial isolation from cell nuclei ('nucleic') and their acidic nature ('acids'). Option D is correct as it encompasses both these reasons for the naming. Options A and C only partially explain the naming, while Option B is irrelevant to the origin of the term.
