Cell Mitosis Simulator (2D)

Interactive 2D top-down simulator of animal cell mitosis: step through interphase, prophase, metaphase, anaphase, telophase and cytokinesis with animated chromosomes, spindle fibers and live cell-biology readouts.

Molecular Biology2DEasy60 FPS📱 Mobile-adapted⇄ 3D version

This 2D top-down simulator walks through a complete round of animal cell mitosis: interphase, prophase, metaphase, anaphase, telophase and cytokinesis, with 4 color-coded chromosome pairs condensing, aligning on the metaphase plate, and being pulled apart by spindle fibers to opposite poles before the cell pinches in two. Use Play for continuous automatic playback, step Prev/Next through each phase manually, jump straight to any phase, and adjust playback speed — the live readout panel tracks the current phase, transition progress, chromatid separation count and elapsed model time.

⚙ Under the hood
