A Molecular Maze It Is
a: Agarose gel ~
b: complex maze with very tiny channels
What: "An agarose gel is like a complex maze with very tiny channels. DNA has a negative charge and will move toward the positive pole in an electrical field. Short pieces of DNA navigate more easily through the maze and therefore move a greater distance. An indicator dye is added to the DNA digest prior to injecting it into the gel so that the researcher can tell when the small fragments have run the length of the gel."
