DNA Fingerprinting

1. DNA is unique for everyone. The only exception is if a person has an identical twin.

2. DNA fingerprints are used for solving crimes.

3. The "crime" that was committed was that someone licked Jimmy's lollipop.

4. The bodily fluid that was removed from the crime scene to get DNA was saliva.

5. A restriction enzyme cuts long DNA molecules at different locations.

6. Agarose gel is a thick, porous, jello-like substance.

7. Electrophoresis is the process of moving molecules with an electric current.

8. Smaller fragments of DNA move more easily than longer strands.

9. You need to place a nylon membrane over the gel because it makes the agarose gel easier to work with.

10. Probes attach themselves to the DNA fragments on the nylon membrane.

11. The chemical that is radioactive in the "virtual lab" is the probes..

13. Based on my DNA fingerprint, Honey licked the lollipop.
