Practice question
Question
The central rod domain of keratin consists primarily of:
Explanation
α-helices accurately describes the structural composition or molecular organization asked about in this question. In Protein Structure, knowledge of molecular structure is directly linked to understanding biological function. The specific arrangement of chemical components in α-helices determines its physical properties, biological activity, and interactions with other molecules. The other options (β-sheets, Random coil, and Loop structures) describe different structural arrangements, incorrect stoichiometry, or compositions of different biological molecules.
