double helices
Twisted genetic ladders
Double helices is the plural of double helix, the twisted-ladder structure formed when two spiral strands wind around each other.
The term is most familiar from molecular biology, where it describes the shape of DNA: two complementary strands coiling together, connected by base pairs like rungs.
The double helices of DNA carry genetic information.
