Mitosis Phases
Step through all 6 phases of the cell cycle: Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis. Each phase features a Canvas 2D cell animation, key events list, DNA content tracker, and chromosome count. Use Auto Play to watch the full cycle.
Cell Membrane Transport
Simulate four types of membrane transport: simple diffusion, facilitated diffusion, active transport (ATP-powered), and osmosis. Adjust inside/outside concentrations and watch particles move across an animated phospholipid bilayer. ATP pump and channel proteins are rendered for each mode.
Enzyme Kinetics
Visualize Michaelis-Menten kinetics with an animated enzyme-substrate particle scene, a live V vs [S] curve, and a Lineweaver-Burk double-reciprocal plot. Adjust Vmax, Km, and highlighted [S]. Switch between no inhibitor, competitive (↑Km, Vmax same), and noncompetitive (↓Vmax, Km same) to see how each changes both graphs in real time.
Mendelian Genetics
Interactive Punnett square builder with four cross types: monohybrid (3:1), dihybrid (9:3:3:1), testcross (1:1), and incomplete dominance. Select parent genotypes via dropdowns to regenerate the square and ratio donut chart instantly. Simulate 100 offspring to compare empirical vs expected ratios. Color-coded cells distinguish dominant, heterozygous, and recessive genotypes.
