Electrophoresis analysis

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

A student performed a gel electrophoresis experiment. The results are represented in the diagram

below. Compared to the fragments at the top of the gel, the fragments at the lower end are

• larger, and move slower

• larger, and move faster

• smaller, and move faster

• smaller, and move slower
