Cell-cycle explorer
Walk the eukaryotic cell-cycle teaching model used before mitosis detail.
What this explorer teaches
Interactive G1 → S → G2 → M timeline with stage explanations.
Learning goal: Anchor DNA replication (S) before mitotic segregation (M).

Educational model — simplified for learning. Not medical advice. Features are conceptual and not drawn to molecular scale unless stated.

How to use this explorer
- Advance with Next / Previous, the step chips, or keyboard ← →.
- On touch devices, tap chips and buttons (minimum comfortable target size).
- If you prefer reduced motion, the site respects
prefers-reduced-motionand jumps between states without animation. - Screen-reader / keyboard users: focus stays on controls; the live region announces the current step.
Scientific notes & limits
The G1–S–G2–M model is a standard eukaryotic teaching cycle. Checkpoints and specialized phases (e.g., G0) matter in advanced courses but are not fully animated here. DNA replication in S produces sister chromatids before mitosis.
