Answer:
Nucleic acids
Explanation:
Nucleic acids are the macromolecule made of a phosphate, sugar ring, and a nitrogen base.
These three components are the major parts of the nucleic acid.
Nucleic acids can differ in the type of nitrogenous bases that they have, because DNA and RNA have different bases.
However, all nucleic acids have a basic unit that is made up of a phosphate group, sugar ring, and nitrogen base.
So, the correct answer is Nucleic acids.
