Question

multiple - choice question
which macromolecule contains phosphorous (p)?
nucleic acids
carbohydrates
lipids

Explanation:

Nucleic acids (like DNA and RNA) have a phosphate group in their structure, which contains phosphorus. Carbohydrates mainly consist of carbon (C), hydrogen (H), and oxygen (O). Lipids also mainly have C, H, and O (some lipids like phospholipids have phosphorus but the general category 'lipids' is not the best answer here compared to nucleic acids which always have the phosphate - containing structure).

Answer:

Nucleic Acids
