1. What is gel electrophoresis used for?
Gel electrophoresis is used to isolate DNA fragments to further analyze and identify.
2. The positive electrode should go at the top (closer to the wells) or at the bottom (farther away from the wells)?
The positive electrode should go at the top (closer to the wells).
3. Is DNA positively or negatively charged? What part of the DNA is negatively charged? Which way does DNA migrate?
The DNA is negatively charged along their length so that it migrates to the positive electrode.
4. After you run the lab, where will the smallest fragments of DNA be located? Why?
The smallest DNA fragments should be father along the agrose gel, because since it is smaller it is able to move easier through the agrose
