DNA helix
Twisted chromosome shape
DNA helix refers to the characteristic spiral structure of deoxyribonucleic acid, the molecule that carries genetic information.
DNA typically forms a double helix—two strands wound around each other like a twisted ladder, with the rungs made of paired chemical bases.
The term appears in both scientific and general contexts: The discovery of the DNA helix revolutionized biology.
