Detailed explanation-1: -The most common types of secondary structures are the helix and the pleated sheet.

Detailed explanation-2: -Protein secondary structure refers to regular, repeated patterns of folding of the protein backbone. The two most common folding patterns are the alpha helix and the beta sheet. In an alpha helix, the polypeptide backbone coils around an imaginary helix axis in clockwise direction.

Detailed explanation-3: -Answer and Explanation: The secondary structure refers to a protein’s polypeptide backbone chain. Alpha helix is one of the secondary structures a protein can have.

Detailed explanation-4: -Answer and Explanation: The correct answer is C. Tertiary. The structure of a protein that comes from the further bending and folding of pleated sheets and helices is the tertiary structure.

Detailed explanation-5: -The tertiary structure of the protein Tertiary structure of the protein is a three-dimensional combination of -helices and -sheets that fold next to each other as a result of noncovalent interactions between amino acids’ side groups and the environment surrounding the single polypeptide.
