Answer:
The correct answer will be- food containing nitrogen and phosphorus elements.
Explanation:
Nucleic acids are the macromolecules which are made up of monomer unit called nucleotides. The two nucleic acids are DNA and RNA present inside us.
Each nucleotide is made up of a five-carbon sugar, a phosphate group and four types of nitrogenous bases (adenine, guanine, cytosine and thymine). So the food should contain these elements mainly nitrogen and phosphorus to make nucleic acids.
The good source of food products which supply phosphorus is - Whole Grains, Chicken, Turkey, Pork, nuts and many more. The food products rich in purines and pyrimidines are sardines, mussels, crab, shrimp and many others.
Thus, food containing nitrogen and phosphorus elements is the correct answer.
