DNA Technology

In preparation for an electrophoresis procedure, enzymes are added to DNA in order to

• convert the DNA into gel

• cut the DNA into fragments

• change the color of the DNA

• produce longer sections of DNA

What is this technique an example of?

• chromatography

• gel electrophoresis

• direct harvesting

• genetic engineering
