Secondary structure of protein includes:
Correct answer: B. Both A and C
- A. α-helix
- B. Both A and C
- C. β-sheets
- D. 3-dimensioal folding
Explanation
Alpha helices (A) and beta sheets (C) are types of secondary protein structures. Alpha helices are right-handed coiled structures, while beta sheets consist of beta strands connected laterally by at least two or three backbone hydrogen bonds, forming a pleated sheet. These structures are part of the secondary structure of proteins, which refers to the local folding patterns of the polypeptide backbone.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
