Explanation:

Proteins are macromolecules composed of amino acids linked together by peptide bonds. Nucleotides are the building blocks of nucleic acids (DNA and RNA). Base pairs are part of the structure of nucleic acids (like in DNA where adenine pairs with thymine and cytosine pairs with guanine), but they are not the fundamental building blocks of proteins.

Answer:

amino acids
