Hydrogen atom vs DNA double helix: length comparison
Hydrogen atom
A hydrogen atom is the simplest neutral atom, with one proton in its nucleus and one electron around it.
105.8 pmCharacteristic size
0 - shared origin
The ring marks the true-scale position of a hydrogen atom; it does not show its width. Only the inset is enlarged (×12.4).
DNA double helix
DNA is the molecule that stores hereditary information in living organisms.
2 nmHelix diameter
0 - shared origin
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions.
