DNA Fingerprinting

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

2. What are DNA fingerprints used for?
Determining Biological Parents or determining a suspect of a crime

3. What “crime” was committed?
Someone licked a NOVA Holographic lollipop

4. What bodily fluid was removed from the “crime scene” to get DNA?
saliva
5. What does a restriction enzyme do?
Restriction enzymes cut long DNA molecules into smaller strands.

6. What is agarose gel?
Agarose gel is a thick liquid that allows smaller pieces of DNA to easily move besides larger pieces.

7. What is electrophoresis?
The process of moving molecules with an electric current.

8. Smaller fragments of DNA move ____________ than longer strands?
easier

9. Why do you need to place a nylon membrane over the gel?
The DNA gets sucked from the agarose gel, making it easier to see.

13. Based on your DNA fingerprint, who licked the lollipop?
Honey Sweet


14. What kinds of things could you do at the DNA workshop?
 You can replicate DNA through the DNA replication process. Also, you can synthesis protein through RNA translation.


15. Read an article about genetics at this site that you might find interesting, or use the "Search" box in the upper right hand corner to search for DNA fingerprinting.
Summarize what the article was about. Write this in a paragraph format.


The Guam Police Department has solved almost 40 cases of robbery or stealing through a new machine that can identify fingerprints. These machines are becoming more common and are expanding in population. With over 25 officers that have been trained in fingerprint analyzation, it is a new way to find suspects in a crime. This technology is still being only used in Guam, but is soon going to go international.
