What Does That DNA Molecule Really Look Like???

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...

Clever! Here is a pattern for a 3' segment of the DNA molecule. Individuals color each nucleotide an assigned color. Then they cut out the pattern and attach the pieces to each other. Finally, they locate a partner in the classroom with...

Three steps are needed to extract DNA from learners' inner cheek cells. The procedure and reasons for each step are explained. As enzymes work on the cells, a series of questions are answered regarding the structure of the DNA molecule....

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...

We are all born with one, but how many people actually know what the pancreas does? Follow along with a short video as it examines the important role this often-overlooked organ plays in digesting food and maintaining healthy blood-sugar...

Hot cocoa is easy to make with only two ingredients, so what does it have to do with chemistry? The lesson begins with what seems like an obvious question. Then scholars perform simulations to focus on phase changes. Lastly, they...

Seeing is believing! Viewers observe the latest in technology—the ability to watch as a protein molecule searches for the appropriate binding site on a DNA molecule! A short video follows transcription factors SOX2 and OCT4 in their...

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...

The shape of a molecule is determined by the arrangement of atoms around the central atom and lone pairs of electrons. Scholars build models of molecules using single, double, and triple bonds. They can then see real molecules bond...
