Unit 11 Lesson 2 http://science.phillipmartin.info DNA Fingerprinting •Gel electrophoresis: a process used to separate DNA fragments of an organism. (Electro= using electricity •Phoresis= to move across) Electricity is used to move the DNA across or through a gel. • DNA Fingerprinting is used to solve crime scenes and in determining the parents of a child (paternity tests). DNA Fingerprinting (continued) DNA can be used like fingerprints to identify a person. Any cell or fluid can be analyzed (blood, hair, skin, fingernail, urine, etc) Used in paternity tests to determine the mother or father of a child. Gel Electrophoresis Gel Electrophoresis Steps: 1. Enzymes cut DNA samples 2. The cut DNA samples are placed in a gel 3. An electric voltage moves the DNA fragments across the gel 4. The smaller pieces of DNA travel the fastest 5. A trail is left for each sample. 6. The trail can be matched to determine if someone is guilty of a crime. Gel Electrophoresis Go to the underlined link and click play.
