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...

Students are able to identify start and stop sequences in DNA. They are able to model using restriction enzyme and ligase to remove sections of DNA and reattach them. Students are introduced to the process of recombinat DNA through the...

Students use the exercise as a prelude to a "wet" lab or as a substitute for such a lab. It correlates well with colony transformation labs. This lab is recommended for students what have difficulty with the abstractions that genetic...

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.

Let's get a closer look at DNA and other molecular structures. The first lesson in the series of four introduces a variety of imagining techniques that engineers and scientists use to visualize molecular structures. The resource presents...

Can your biology class crack the Case of the Crown Jewels? Junior forensics experts try their hands at DNA restriction analysis in an exciting lab activity. The lesson introduces the concept of restriction analysis, teaches pipetting and...

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...

Students use their knowledge of DNA fingerprinting to evaluate the use fingerprints in courts, and will address the ethics of establishing a national database of fingerprints.

Learners explore DNA fingerprinting. Students discover how DNA fingerprinting is done and judge the validity. They evaluate the use of certain prints in courts and address the ethics of establishing a national database of fingerprpints.
