Multiple Choice
In the context of protein structure, what is the monomer (basic building block) of a protein?
A
A nucleotide
B
A monosaccharide
C
A fatty acid
D
An amino acid
Verified step by step guidance1
Understand that proteins are large biomolecules made up of smaller units called monomers.
Recall that the monomers of proteins are amino acids, which link together via peptide bonds to form polypeptides.
Recognize that nucleotides are the monomers of nucleic acids (DNA and RNA), not proteins.
Know that monosaccharides are the monomers of carbohydrates, and fatty acids are components of lipids, not proteins.
Therefore, identify that the basic building block (monomer) of a protein is an amino acid.
