Verified step by step guidance1
Understand that proteins are large biomolecules made up of smaller units linked together in a chain.
Recall that the basic repeating unit (monomer) of a protein is the molecule that links together to form a polypeptide chain.
Identify the four options given: Amino acid, Nucleotide, Fatty acid, and Monosaccharide, and consider which is commonly known to form proteins.
Recognize that nucleotides are the monomers of nucleic acids (DNA and RNA), fatty acids are components of lipids, and monosaccharides are the monomers of carbohydrates.
Conclude that amino acids are the monomers that link via peptide bonds to form polypeptide chains, which fold into functional proteins.
