DNA is found in the nucleus of cells. Our bodies are made of cells. Each person has a particular DNA in the nucleus of their cells. If you can get a sample of a person’s cells, like a hair or a drop of blood, you can see what their DNA looks like in a lab. A suspect’s DNA can be compared to DNA found at a crime scene.
In the game csi: Squeak Sneak, Fetch’s squeaky toy is missing. Look at the crime scene and collect evidence. Use DNA to finger the real culprit.
Now watch the Dragonfly TV Forensic Whodunnit Video: The Cake Caper. Somebody has tampered with a birthday party table. The investigaters find fiber, saliva and fingerprint evidence at the crime scene, so they gather fiber, saliva and fingerprint samples from everyone they think is a suspect. Watch them analyze the evidence using a forensics lab to help solve the mystery.
Next, use an online lab to do some DNA testing. Read the mystery to understand what evidence has been collected and who the suspects are. Then follow the directions in the online lab to do the DNA testing yourself.
