A. Three microtubule fibers that
direct where protein motors walk.

B. Green: Dynein protein motor carrying a red cargo from the nucleus (left) to the edge of the cell (right).

C. Red: cargo is a stop signal during cell division (mitosis).

D. Blue: protein motor can carry a cargo from the edge of a cell to the nucleus.

E. A protein motor is made of many different molecules

0:00 The molecular machines (now named protein motors) in animation.

0:46 DNA needs protein motors to do the work of separation during cell division.

1:17 Copying DNA.

2:24 Leave animation of nucleus.

2:33 View cell division with a microscope.

3:24 One chromosome on a microtubule fiber in animation.

3:45 Microtubules attached to chromosome kinetochore.

4:40 Dynein protein motor.
