To learn more about gel electrophoresis, one can Google it. There is also a whole Wikipedia article dedicated to gel electrophoresis, and it happens to be quite informative.
Why is DNA cut up before it is put into a gel?
Assuming you're talking about an electrophoresis gel for separating DNA: DNA is itself negatively charged because it contains phosphate groups. Thus, when you apply a current, it will move towards the positive electrode at the other end of the gel. If the DNA were placed at the positive end of the gel, it would migrate backwards and you'd lose the sample.

What purpose is gel electophoresis used?
It consists out of a polymer with pores in it. Just imagine many spiderwebs that are woven one into another, so that you get a complicated 3D net. The holes that remain are used to separate molecules. The shorter a molecule, the easier it will find a way through the web. Thus it will take a shorter time for a small molecule to reach the end of the gel.
In gel electrophoresism DNA fragments migrate toward one end of a gel because that are?
DNA is naturally negative therefore when a positive charge in put to one side of the gel the DNA wants to move towards it.

Describe how do different fragments of DNA show up on a gel?
the chamber has a positive end and a negative end...the DNA moves through the gel toward the positive end (because DNA is negative). The smaller fragments move faster, therefore going further, and the larger pieces stay closer to the wells. what is DNA gel
