Interactive explorers
Rich educational visualizations for DNA packaging, chromosomes, cell division, and gene expression. Each explorer has a guided interactive model plus full text explanations — content is never locked inside canvas pixels alone.
How to use
- Use step buttons, keyboard arrows, or on-canvas controls — hover is never required.
- Read the live caption and the page’s written sections for the same ideas.
- Models are simplified for teaching and are not drawn to molecular scale unless stated.
