The sequence of amino acids combined in a peptide chain is called the _.
Correct answer: A. Primary structure
- A. Primary structure
- B. Secondary structure
- C. Tertiary structure
- D. Quaternary structure
Explanation
A peptide bond is made up of many amino acids condensing to form peptide bonds. Peptide chains are made up of many peptide bonds condensing to form chains. The sequence of amino acids is the primary structure and the hydrogen bonding between amino acids is the secondary structure. Various peptide bonds forming chains and joining together is the tertiary structure.
