What are the layers in basal body of flagelle |
| Answer» The\xa0flagellum\xa0of E. coli consists of three parts, filament, hook and\xa0basal body, all composed of different proteins. The\xa0basal body\xa0and hook anchor the whip-like filament to the cell surface. The\xa0basal body\xa0consists of four ring-shaped proteins stacked like donuts around a central rod in the cell envelope.\xa0A bacterial\xa0flagellum\xa0has 3 basic\xa0parts: a filament, a hook, and a basal body. 1) The filament is the rigid, helical structure that extends from the cell surface.\xa0The\xa0basal body\xa0of a bacterial\xa0flagellum\xa0is a rod and a system of rings embedded in the cell envelope. ... The rod is a major component of the\xa0flagellar basal body\xa0and it spans the bacterial periplasm. The L and P rings are not found in Gram-positive bacteria. | |
