A molecular motor that can navigate a network of tracks. The motor mechanism is shown in the top of the picture (the motor, in red, steps from left to right). We tested the motor on branched tracks (bottom left) and showed that it can be sent along any of the four branches. The motor can be controlled by sending instructions (turn right then left) or the motor can carry its own instructions.
DNA: the phosphate backbone of two strands twist around each other to make the familiar double-helix structure with a ladder of hydrophobic bases stacked on the inside.
