Nitrogen is an essential component for living cells, as it is involved in synthesis of amino acids and nucleic acids. These amino acids polymerize to form proteins. So the organic macromolecules do living things build using nitrogen is protein and nucleic acids, i.e., option a and d.
What are amino acids?Amino acids are the smallest unit or one can say building block of protein.
It usually have an amino group and a carboxyl group and a side chain. It is linked together by peptide bonds.
As it has an amino group, it requires nitrogen for its formation, and it will ultimately form protein.
Nitrogen is also required for the formation of nucleic acids i.e., DNA and RNA.
Thus, the correct option is a and d.
