Question Detail
Question
The primary structure of a protein refers to: A. Alpha helix b. 3D folding c. Sequence of amino acids d. Association of subunits
Correct Answer
Option C is the correct answer.
Detailed Explanation
The primary structure of a protein is the linear sequence of amino acids in the polypeptide chain. This sequence is determined by the gene encoding the protein. The alpha helix is a secondary structure, 3D folding is tertiary, and subunit association is quaternary.
Hint
It's the simplest level – just the order of the amino acid building blocks.
