Detailed explanation-1: -Answer and Explanation: The classes of macromolecule that contain the most phosphorus are equally the nucleic acids and the lipids. Nucleic acids in DNA or RNA contain a single phosphate group, which contains phosphorus.

Detailed explanation-2: -Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P). Nucleic acids are very large macromolecules composed of repetitive units of the same building blocks, nucleotides, similar to a pearl necklace made of many pearls.

Detailed explanation-3: -Key points. Phosphorus is an essential nutrient found in the macromolecules of humans and other organisms, including DNAstart text, D, N, A, end text.

Detailed explanation-4: -We have lipids, Proteins, nucleic acids and carbohydrates, which one has a phosphate group.

Detailed explanation-5: -Phosphorus is an essential component of all cells; the element forms the backbone of nucleic acids, without which cells cannot reproduce. Phosphorus is also incorporated in nucleotides, sugars, proteins, and lipids.
