Fill in the blanks:
After DNA is isolated from living cells and treated with enzymes to break it up, it must be run through a gel (shown here) to visualize the result of the experiment. The gel acts like a filter and slows the largest pieces of DNA the most. Charge is used to move DNA through the gel; DNA is negatively charged and will move towards a positive charge. Fill in the blanks with either "shortest" or "greatest". Based on this information, the largest DNA molecules will travel the __________ distance through the agarose gel during the experiment, while the smallest DNA molecules will travel the ________ distance through the agarose gel during the experiment.
