Question

Quizplus · Accepted Answer

The primary structure of a protein refers to the sequence and number of amino acids in the polypeptide chain.

Answer: B
 The secondary structure of a protein refers to the local folding patterns of the polypeptide chain, specifically the formation of alpha helices, beta sheets, and turns.

Answer: C
 The tertiary structure of a protein refers to the overall three-dimensional shape of the protein, which is determined by interactions between amino acids that are not adjacent in the polypeptide chain, such as disulfide bonds, hydrogen bonds, and hydrophobic interactions.

Answer: D
 The quaternary structure of a protein refers to the arrangement of multiple protein subunits, if present.
