New cards

What is a gel electrophoresis used for and how it works (draw it)

And describe what kind of molecule DNA is and what it will move towards

How is the banding pattern created and what feature does it have to the individual

Used to compare DNA samples. DNA samples are loaded onto a gel with a buffer and separated using an electrical current

DNA is a negatively charged molecule, therefore it will always move towards the positive electrode

DNA fragments are all different lengths which means that the shorter ones move through the gel quicker which creates the banding pattern that is unique to an individual
