Question

macromolecule containing hydrogen, oxygen, nitrogen, carbon, and phosphorus
choose an answer
1 amino acid
2 carbohydrate
3 nucleic acid
4 protein

Explanation:

Nucleic acids (like DNA and RNA) are macromolecules. Their structure includes a phosphate group (with phosphorus), a sugar (with carbon, hydrogen, oxygen), and a nitrogenous base (with nitrogen). Amino acids (proteins' building blocks) mainly have C, H, O, N. Carbohydrates have C, H, O. Proteins (polymers of amino acids) have C, H, O, N (sometimes S). The given macromolecule with C, H, O, N, P matches nucleic acid's composition.

Answer:

1. Nucleic acid
