DNA Fingerprinting

Seventh-graders come in to science class to find a file on their desks detailing a crime to be solved! As a demonstration, you simulate the restriction of DNA samples and separate them by electrophoresis. From the gel, learners can...

Everyone loves a good mystery ... can your class actually solve one? Partnered pupils take on the role of forensic investigators during a three-part activity focusing on DNA evidence processing. Learners discover the methods used to...

Students use the prelab as an introduction to the importance of DNA fingerprinting- a form of identification that us being accepted by both scientific and leagl experts. They prepare a gel for electrophoresis. DNA fragments, which have...

Ever wonder how scientists determine how animals are related, or who is guilty of a crime? Discover gel electrophoresis in an easy-to-understand video from a fun biology playlist. Topics include how restriction enzymes create segments of...

Match up the DNA code. Pupils read the website from the American Museum of Natural History about how DNA can determine whether a skin is from a particular type of reptile. Using the same technique, learners match up products with the...

Show your class why restrictions aren't always a bad thing. In the third segment of a four-part series, the instructor develops the idea of restriction enzymes. Pupils learn how scientists use restriction enzymes in DNA analysis and DNA...

Ever wonder how they solve those mysterious murders in TV crime dramas? The second of four units in a Biotechnology series introduces scholars to the many methods of DNA analysis. Pupils create and run their own gel electrophoresis...

The chances of a DNA mismatch occurring in DNA fingerprinting is one in a billion. Here learners see how using the differences in people's DNA, specifically Short Tandem Repeats (STRs), cutting them out using restriction enzymes, and...

Use food coloring in electrophoresis. The last segment in a four-part series mimics DNA fingerprinting by using chromatography. Teams conduct chromatography on food coloring to find colors that use similar pigmentation in their makeup.

Students study the process of DNA Fingerprinting and how DNA Fingerprinting is used in solving crimes. They examine a crime scenario that involves collecting DNA Fingerprinting information from blood collected at the crime scene. They...
