Identify the monomer subunits of proteins

Proteins are biological macromolecules (polymers) constructed from monomeric building blocks called amino acids, which are linked together by peptide bonds.

Evaluate the given options

• Nucleic acids are the building blocks of DNA and RNA, not proteins.
• Fatty acids are components of lipids (such as triglycerides), not proteins.
• Amino acids are the monomeric units that polymerize to form proteins.
