the agarose gel is positively charged
In gel electrophoresis, the largest DNA fragment will appear
closest to the starting wells
farthest from the starting wells
three quarters away from the starting wells
it depends on how many fragments there are
It allows for strands of DNA to be cut into various lengths for testing

What is the function of the gel in Gel Electrophoresis?
extract DNA from the liquid
filter the DNA as it moves through the electrophoresis apparatus
buffer the DNA so it keeps moving
charge the DNA so it will move to the opposite side of the system
