Nazi stormtroopers stopped opposition deputies going in, and beat up anyone who dared to speak against it. The Enabling Act made Hitler the dictator of Germany, with power to do anything he liked-legally.
There are three types of myofilaments: 1  Thick filaments, composed of protein molecules called myosin. In striations of muscle bands, these are the dark filaments that make up the A band.  Thin filaments are composed of protein molecules called actin.
They are composed predominantly of a contractile protein called actin, which is the most abundant cellular protein. Microfilaments' association with the protein myosin is responsible for muscle contraction. Microfilaments can also carry out cellular movements including gliding, contraction, and cytokinesis. Microtubules are cylindrical tubes, 20-25 nm in diameter. They are composed of subunits of the protein tubulin--these subunits are termed alpha and beta. Microtubules act as a scaffold to determine cell shape, and provide a set of tracks for cell organelles and vesicles to move on.
