[Q]: Members of the genus aeromonas have polar and lateral types of these, and it has a paracrystalline filament running along its length in T. brucei. In some organisms, a MS ring and a periplasmic P ring are found at its base, and a June 2008 study in Science discusses a protein that acts a clutch to halt the rotation of these. Their components are connected by nexin linkages, and dyneins generate the force which causes a bending motion in eukaryotes, wherein they have a 9+2 arrangement of microtubules that form an axoneme. For 10 points, identify these structures consisting of hooks and filaments in basal bodies, present in euglena and sperm cells, which allow for motility of the cells.
