What are the monomers that make up proteins?

• A. Amino acids
• B. Nucleotides
• C. Fatty acids
• D. Monosaccharides

Answer: (A)

Verified step by step guidance

1. Understand that proteins are large, complex molecules that play many critical roles in the body. They are made up of smaller units called monomers.
2. Identify the four options given: Amino acids, Nucleotides, Fatty acids, and Monosaccharides.
3. Recall that amino acids are the building blocks of proteins. Proteins are polymers made by linking amino acids together in a specific sequence.
4. Recognize that nucleotides are the monomers of nucleic acids, such as DNA and RNA, not proteins.
5. Understand that fatty acids are components of lipids, and monosaccharides are the monomers of carbohydrates, neither of which are related to the structure of proteins.
