DNA Fingerprints

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...

Has your class ever been astounded by the complexity of DNA analysis? Have they ever asked why genetic engineering has become so important to our daily lives? Young scientists perform DNA extraction on strawberries and explore how the...

What is in that double helix? Explain intricate concepts with a variety of creative activities in a instructional activity that incorporates multiple steps to cover DNA structure, nucleic acids, and proteins. Pupils explore the history...

It has been decades since the discovery of DNA. Still, activities such building this DNA model allow blossoming scientists to better understand the components that form this overall structure. During this activity, they will also...

Uncover the basics of DNA structure through exploration activities. Collaborative groups build DNA models and recreate the process of replication. Then, using plant cells such as peas or strawberries, they extract a DNA sample.

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...

Discusses the scientists who made discoveries about DNA and those who invented and worked on DNA fingerprinting, and some of the criminal cases that were resolved or thrown out through the use of DNA evidence. (Warning: Some of these...

You can use these slides to explain the many complicated steps of the Polymerase chain reaction. The diagnostic and forensic uses of gel electrophoresis are detailed. This PowerPoint could be used to communicate facts, and also to prompt...

In order to understand DNA fingerprinting, advanced biology aces divise a crime scenario and analyze three different samples of lambda DNA. This creative lesson plan provides practice with micropipettes, electrophoresis boxes, and other...
