HelixQuest — a molecular-biology world of DNA, genes and enzymes

🎓 Ages 15–18 · Grades 9–12 · Science / Biology

HelixQuest

You don’t learn genetics by memorizing ratios — you learn by predicting them. Set up a cross, say how the offspring will sort, and a real Punnett-square engine computes it right on your device to check you. Real monohybrid, dihybrid, and test crosses; no hand-waving, nothing sent anywhere, and a wrong guess is the fastest way to see how the alleles actually assort.

Who you’ll meet

Not mascots — working biologists (and a couple of famous ones), each showing a single idea in action. You’ll run into them across the kits and the bench.

  • Mendel — tracks how alleles assort into offspring ratios (inheritance)
  • Rosalind — reads the double helix as the molecule that stores the code (DNA structure)
  • Cyra — copies the genome exactly before a cell divides (mitosis)
  • Meira — halves and shuffles the genome to make variation (meiosis)
  • Sol — captures light energy into sugar (photosynthesis)
  • Otto — releases the energy stored in sugar (cellular respiration)
  • Darwin — lets the fittest variants leave more offspring (natural selection)
  • Vera — keeps the internal balance steady against change (homeostasis)
  • Cat — speeds a reaction without being used up (enzymes)
  • Dr. Okafor — the mentor — predict the outcome, run the model, then reconcile

How it works

HelixQuest is written to trust you — it’s about reasoning through how genes behave, not memorizing ratios, and a wrong prediction is just a place to learn. The Genetics Bench is a small, exact engine: no server, nothing sent anywhere. Your progress is saved only on this device: no accounts, no ads.
