A helix is formed by a polypeptide chain with repeating phi and psi angles. Its geometry is defined by the number of residues per turn, and the rise per residue. In principle the polypeptide chain can form right and left handed helices with a range of pitches.

In simpler terms, a helix is a twisted shape: like a spring, screw, or spiral. In mathematics, a helix is a curve in 3-dimensional space.

There are many definitions one them being that it is 'a spiral stair case. To find out other definitions go to Good and in the search bar type in: Define: Helix and you will get the other definitions.

It's any spiral shaped structure. Have a look at the link below for a better description.
Remember - DNA is a DOUBLE-helix... :)

Picture a spring, like the one in a pallpoint pen.
