The sequence of amino acids combined in a peptide chain is called _.
Correct answer: A. Primary structure
- A. Primary structure
- B. Secondary structure
- C. Tertiary structure
- D. Quaternary structure
Explanation
A protein molecule is made up of many amino acid molecules which are attached by peptide bonds. The linear sequence of amino acids within a protein will be its primary structure therefore, the answer is A.

About Proteins
Proteins are polymers of amino acids joined by peptide bonds, and their function depends on primary, secondary, tertiary and quaternary structure. The topic covers fibrous and globular proteins, enzymes, antibodies, hormones and transport proteins, as well as denaturation by heat or extreme pH.
