Caption: The DNA gel is composed of stiff DNA nanotubes connected to each other via long, flexible DNA linkers. A motor protein, FtsK50C, binds to special sites on the linkers. When ATP, a biochemical fuel, is allowed to permeate the gel, the motor molecules reel in the linkers to which they are bound, drawing nanotubes together, and stiffening the gel.
