double helixes
DNA's signature shape
Double helixes is the plural of double helix, the spiral-staircase structure formed when two strands wind around each other.
The term is most associated with DNA, whose twin strands coil around a central axis: Watson and Crick described DNA's structure as a double helix.
The alternative plural double helices appears in more formal scientific writing.
