Quizplus · Accepted Answer

The protein has two secondary structure elements: a beta-sheet (F1F1F1S1βF1F1F10) and an alpha-helix (F1F1F1S1αF1F1F10). Option A and B both incorrectly identify an additional beta-sheet element, while option D and E incorrectly identify an additional alpha-helix element. Therefore, C is the best choice as it correctly identifies the two secondary structure elements present in the protein.
