Consider the movement in the host cell of two intracellular pathogens, the herpes simplex virus (H) and the bacterium Listeria monocytogenes (L). Indicate whether each of the following descriptions better applies to the virus (H) or the bacterium (L). Your answer would be a four-letter string composed of letters L and H only, e.g. HLLL.
( ) It moves by a "pushing" mechanism (as opposed to a "pulling" mechanism).
( ) It can collide with the plasma membrane and create long, thin protrusions from the cell that can then be engulfed by a neighboring cell.
( ) Its movement is powered by ATP hydrolysis by kinesin and dynein motors.
( ) Its movement relies on dynamic cytoskeletal filaments.
