What Does That DNA Molecule Really Look Like???

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...

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...

DNA molecules hold the secrets that make us unique. The fourth of 12 lessons explores the structure of DNA by building candy models. After building the models, young scientists break their models to begin the process of DNA replication....

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....

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...

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...

Raindrops are more like pancakes than teardrops. Scholars learn the physics behind the shape of a falling raindrop in a video lesson presentation. An episode explains the forces acting on the droplet and how those forces change as it...

One of the first models of DNA appeared to be a triple helix. Young scientists learn about the many scientists who worked to find the shape of DNA. They observe multiple models, tests, and experiments to understand the conclusions. An...

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...

Show your class why restrictions aren't always a bad thing. In the third segment of a four-part series, the instructor develops the idea of restriction enzymes. Pupils learn how scientists use restriction enzymes in DNA analysis and DNA...
