DNA: The Double Helix

For Students 9th - 12th Standards
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...

The DNA Molecule Is Shaped like a Twisted Ladder

For Students 9th - 12th Standards
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...
