Gel Electrophoresis• Moves DNA because it is negative
• Separates DNA fragments based on size
• The smaller the fragment the farther it will move
• Can compare DNA from individuals

Recombinant DNA
When a piece of foreign DNA (in purple) is added to a bacterial plasmid (a circular piece of DNA in bacteria), the end result is known as recombinant DNA

How to make recombinant DNA: take a gene (piece of DNA) from a human cell and combine it with a plasmid from a bacteria using restriction enzymes.
