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
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.

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...
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...
Concord Consortium
Protein Folding
Long strings of amino acids fold themselves into stable peptides. The simulation allows scholars to observe the process in multiple ways. Using hydrophobic, hydrophilic, or a combination of proteins in three different solutions, the...
Concord Consortium
Protein Folding Exploring
The potential energy of peptides varies over time as they fold. An exploratory simulation encourages pupils to play with various strands of amino acids to observe the folding and potential energy levels. Young scientists generate all...
Concord Consortium
Polar and Non-Polar Interface
Why is there so much frozen water at Earth's poles? Because water is a polar molecule! Young scientists observe polar molecules moving in a mixture of oil and water. They see the changes in potential energy in the hydrophilic and...

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
Molecular Sorting
Can scientists sort molecules based on their interaction with oil and water? The simulation demonstrates how this is possible. Pupils decide when to insert a molecule and observe how they sort themselves based on polarity.
Concord Consortium
Micelles
Micelles consist of an aggregate of molecules in a colloidal solution. The simulation presents two different ways the molecules assemble into micelles based on the polarity of the solution in which they are placed. Scholars can set the...
