Question

Bacterial flagella is made up of

Answer 1

Flagella-

1. Flagella are the hair-like extensions in the body of bacteria that are used for locomotion in them.
2. It consists of three parts- filament, hook, and the basal body.
3. The filament of bacteria is a helical structure.
4. It is rigid and extends from the surface of the cell.
5. It is composed of a special protein, i.e. flagellin.
6. The protein flagellin is present in a helical chain that forms a hollow core.
7. During the synthesis of filament, the flagellin molecules come out of the ribosomes and get transported to the hollow core of the filament.
8. In the hollow core, the flagellin attaches to the growing tip of the filament.
9. Flagellin causes an increase in the length of the filament.

Final answer: Bacterial flagella are made up of flagellin.
