Nucleosome
See how 2 metres of DNA folds into a 10 µm nucleus. Explore the nucleosome in 3D — click the 8 histones (2 each of H2A, H2B, H3, H4), the DNA wrapped 1.65 turns, and the H1 linker. Then switch to DNA Packing and coil the 'beads on a string' into the 30 nm chromatin fibre, watching the packing ratio climb.

DNA Packaging
Drag one slider and watch 2 metres of DNA fold all the way down to a 10,000× compacted chromosome. Walk the five packing levels in 3D — naked double helix → nucleosomes (beads-on-a-string) → 30 nm chromatin fibre → looped domains → the condensed metaphase chromosome — with the packing ratio climbing 1× → ~10,000× at every step.
