Primary structure of proteins determines__________?
Correct answer: C. Amino acid sequence
- A. Number of polypeptide chains involved
- B. Bending of polypeptide chains
- C. Amino acid sequence
- D. Coiling of polypeptide chains
Explanation
The primary structure of a protein is the exact linear sequence of its amino acids, joined by peptide bonds. Coiling and bending describe higher levels of structure, so students may incorrectly choose coiling of polypeptide chains.
