HelixA helix is a three-dimensional curve shaped like a cylindrical coil spring, characterized by a constant angle of tangent lines to a fixed axis. Notably important in biology, helices form structures such as the DNA molecule's double helix and various protein configurations. Helices can be right-handed or left-handed, and they are defined mathematically as curves with constant curvature and torsion, resulting in forms that appear in nature and technology, including screw threads and the structure of certain molecular compounds. The term originates from the Greek word for "twisted" or "curved." (Source: Wikipedia)
