I Can Do That: Dna Introduction

Civil rights meets biotechnology in a instructional activity that scrutinizes the collection of DNA of citizens who have been arrested, but not yet convicted of a crime. Real-life cases are examined in which the DNA of a relative was...

Is DNA still present after picking fruit or cooking vegetables? Biology scholars extract and collect DNA strands in an impactful lab. Working groups prepare their samples and compare their results to negative and positive standard...

Can turning on the television lead to toxins in the food supply? The lesson offers an opportunity for young scientists to complete guided research. A worksheet lists each question as well as the web page necessary to answer the question....

Students observe the experimental process called bacterial transformation and demonstrate phenotype changes in bacteria that have been transformed with an antibiotic-resistance gene and a metabolic marker. They create a luminescent...

Just how long can a fossil preserve DNA? It seems that DNA becomes unreadable after about 6.8 million years. Learn about the science that helped make this conclusion and the mistakes made along the way in a lesson from a PBS Eons video...

How does DNA work? Young geneticists see how function follows form with a video from Socratica's playlist that explores biology. The narrator pulls apart the double helix and describes each portion, discusses Chargaff's rule, and...

Students describe the structure of DNA and its components and can comprehend that real DNA and its cartoon representation are very different. They are able to link DNA to genetic make-up.

Young biologists explore the theories of DNA replication, learning about the Meselson-Stahl experiment and how it proved DNA replication through semiconservative replication. The video reviews the parts of DNA and then delves...

High school learners read and discuss an article about genetic ancestry and genetic ancestry testing. They complete a paper and pencil activity that mimics the function of a DNA microarray and consider the ethics of genetic testing in...

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...
