A ____ is a small ring of DNA found in a bacterial cell.

• virus
• plasmid
• gene bullet
• PCR

Why is DNA fingerprinting used?

• To determine who is the child's father
• Link suspects to a crime scene
• Determine which species are most closely related
• all of the above

In gel electrophoresis, DNA moves to the

• postive pole

• negative pole

In gel electrophoresis, smaller DNA fragments

• move at a higher speed

• end up closer to the starting point

These are used to cut genes in both recombinant DNA research and DNA fingerprinting

• Clones
• Plasmids
• Probes
• Restriction Enzymes
