DNA Technologies

Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

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...

Before a cell replicates, its DNA must replicate. Take advantage of a hands-on guided lesson plan to teach budding scientists how this happens. Using a set of nucleotide cards, learners become the DNA and work to create matching strands...

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.

This nine-page biotechnology resource contains six pages of questions regarding DNA technology. Questions cover cloning, restriction enzymes, the polymerase chain reaction, different techniques, the human genome project, and more. The...

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...

One of the first biotechnology breakthroughs occurred in 1982 with the creation of synthetic insulin. Young scientists learn about DNA technology with a presentation and accompanying worksheet. It focuses on DNA extraction and...

Did you know that your DNA can be damaged tens of thousands of times per day? Learn about the ways that damage to just one strand of your DNA can be fixed, or in extreme examples, result in genetic mutation such as cancer. 

Start seeing double. The American Museum of Natural History website provides pupils with information about Dolly, the cloned sheep. Learners find out the procedure used to create Dolly along with why scientists clone animals.

Biotechnology changes lives every day, but how did it all start? Learn about Cohen and Boyer's technique for recombinant DNA and the founding of this new scientific study. Then, scholars use the online interactive to discover how Hanahan...
