DNA: The Double Helix
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...

DNA to Protein
Starting from a view of cells, a constructive simulation shows every step of building a new protein. It walks through transcription, translation, building amino acids, and folding the protein. Viewers control if it plays as a video or...

Virtual Lab: DNA - Dye Binding: Equilibrium and Buffer Solutions
Your class is bound to be fascinated by this virtual lab! Young biochemists explore molecules that bind to specific sites on the DNA molecule through a skillful simulation. The lesson challenges learners to create a DNA-bound solution...
Concord Consortium
Modeling Transcription
Transcription makes copies of the instructions inside all living things. Scholars use the simulation to separate DNA and transcribe the RNA. They see a demonstration of the nucleotide pairings as well as the start and stop instructions.
Concord Consortium
Mutations
Are some mutations more damaging than others? An engaging simulation encourages scholars to alter DNA through insertion, deletion, and substitution. It then forms resulting amino acids—or not—and the resulting protein—or not—depending on...

Visualizing Gene-Expression Patterns
How do genetics gurus know so much about gene expression? See traits materialize before your very eyes using a presentation with embedded simulations. Science scholars develop an understanding of the techniques used to follow the work of...

3D Exploration of Bound Antibody and Antigen
Our body manufactures antibodies that are the exact shape for the antigens it encounters. The simulation shows a 3-D model of an antibody and antigen pairing. It allows young scientists to explore the complementary shapes.
Concord Consortium
Modeling Translation
An mRNA sequences make proteins, the most common molecules in cells. Young scientists observe translation of mRNA on ribosomes. They view them forming amino acids. Finally, the amino acids curl into proteins.
