Question

which macromolecule provides the blueprint for living things by storing and transmitting genetic information?
○ protein
○ lipid
○ nucleic acid
○ carbohydrate

Explanation:

To determine the macromolecule that stores and transmits genetic information, we analyze each option:

• Protein: Involved in structure, enzymes, etc., not genetic info storage.
• Lipid: For energy storage, cell membranes, not genetic info.
• Nucleic acid: Includes DNA (stores genetic info) and RNA (transmits it), matching the description.
• Carbohydrate: For energy, structure (e.g., cell walls), not genetic info.

Answer:

C. nucleic acid
