Multiple Choice
In protein biochemistry, what is the monomer (basic building block) of a protein?
A
A nucleotide
B
An amino acid
C
A fatty acid
D
A monosaccharide
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 fatty acids are components of lipids, and monosaccharides are the monomers of carbohydrates.
Therefore, identify that the basic building block (monomer) of a protein is an amino acid.
