Right handed and left handed helix
WebQuestion: Part D - Exploring a helix direction (handedness) You'll probably recall that double-stranded DNA forms a right-handed helix, but you may not know which way a helix twists to be right-handed or left-handed. Here's an easy way to figure it out. Start at the bottom of the helix and imagine it is a spiral staircase. As you walk up the staircase, take note of WebDNA (shown at the left) is a right handed helix. B. The ‘rise’ of the helix’ is the same as that of a normal carpenter’s wood screw (shown at center).

Helices can be either right-handed or left-handed. With the line of sight along the helix's axis, if a clockwise screwing motion moves the helix away from the observer, then it is called a right-handed helix; if towards the observer, then it is a left-handed helix.
