helix

     

A helix (pl: helices), from the Greek wor έλικας/έλιξ, is a three-dimensional, twisted shape. Common objects formed like a helix are a spring, a screw, and a spiral staircase (though the last would be more correctly called helical). Helices are important in biology, as the DNA molecule is formed as two intertwined helices, and many proteins have helical substructures, known as alpha helices.

Trivia about helix

  • DNA is a double one of these
  • Pauling found an "alpha" type of this spiral in proteins; Watson & Crick found a "double" one in DNA
  • A spiral-shaped curve; the threads on a tapered screw form a conical one
  • Pauling found an "alpha" type of this spiral in proteins; Watson & Crick found a "double" one in DNA
  • (Sarah of the clue crew gives the clue) On the surface of a cylinder rising at a constant angle lies this three-dimensional curve whose name is from the Greek for "spiral"
  • It's another term for a spiral, especially when talking about spiraled strands of DNA
