On the left, а bоx lаbeled Pоwer Sоurce hаs two cables extending from it. The top cable has a pink circle with a minus sign indicating the negative terminal, and the bottom cable has a green circle with a plus sign indicating the positive terminal. The cables connect to a rectangular chamber containing a gel. At the top of the chamber, three wells are shown with test tubes inserted into them. Inside the chamber, the gel matrix is labeled on the right side. Within the gel are three vertical columns of blue horizontal bands representing DNA fragments at various positions. The bands in each column are distributed at different heights throughout the gel, showing the separation pattern of DNA fragments. In gel electrophoresis, DNA runs from the top (-) of the gel toward the bottom (+). Why?
