Which of the following is NOT a component of bacterial flagella?

• A. Flagellin
• B. Basal body
• C. Tubulin
• D. Filament
• E. Hook

Answer: (C)

Verified step by step guidance

1. Understand the structure of bacterial flagella: Bacterial flagella are composed of three main parts: the filament, the hook, and the basal body.
2. Identify the protein components: The filament is primarily made of a protein called flagellin.
3. Recognize the function of the basal body: The basal body acts as a motor, anchoring the flagellum to the cell wall and membrane.
4. Understand the role of the hook: The hook connects the filament to the basal body and acts as a flexible joint.
5. Identify the incorrect component: Tubulin is a protein that is not found in bacterial flagella; it is a component of eukaryotic microtubules.
