DNA

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...

A pinch of adenine, a dash of thymine and ta-da, you have life! Well, it's not quite that simple, but through this series of activities and experiments young scientists learn about the structure of DNA and how it contains the recipe for...

Help your class unravel the mystery of DNA with a comprehensive life science presentation. Slide-by-slide this presentation takes young biologist on an exploration of the structure of DNA, its ability to self-replicate, and common...

DNA forms a double helix, but that is not what it looks like. A fact-filled video takes on this inaccuracy as part of an extensive playlist on biology. It shares the recent discoveries about what DNA looks like as well as the many...

DNA carries the code for all living organisms, yet it is made up of only four building blocks. The video explains the structure of DNA down to the nucleotides. It provides the relationships between thymine, cytosine, adenine, and guanine.

Explaining exactly how DNA works to provide genetic information is a complex topic, but it is presented in a clear and engaging way through a five-minute video. Have learners try to explain how DNA works before watching the video, then...

Picture a double helix as a twisted ladder. Scholars see this image through a simulation that allows young scientists to observe a small fragment of DNA in many different formats. They compare the models, colors, bonds, and strands as...

Introduce biology classes to the structure of DNA, the role of genes, and how mutations occur with this nifty resource. After viewing an animated video, discuss the accompanying Think questions and then explore the myriad of additional...

Deoxyribonucleic acid, or DNA, is in every molecule of every known living organism and many viruses. Wouldn't it be great if we could make DNA work to solve crimes and cure diseases? An exciting virtual field trip encourages...
