Detailed explanation-1: -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.

Detailed explanation-2: -Nucleic acids are made of nitrogen-containing bases, phosphate groups, and sugar molecules. Each type of nucleic acid has a distinctive structure and plays a different role in our cells.

Detailed explanation-3: -Nucleic acid contains phosphoric acid, sugar and a nitrogenous base. Q. Polynucleotides are called nucleic acids. Each nucleotide is made up of three parts, i.e, a pentose sugar, a heterocyclic nitrogenous base and phosphoric acid.

Detailed explanation-4: -Phosphorus is found in both DNA and RNA, as it is the nucleic acid’s backbone. The presence of phosphoric acid causes nucleic acids to be acidic. Phosphate + sugar + nitrogenous base = nucleic acid. DNA is made up of deoxyribose, a nitrogenous base, and phosphate.
