This a diagrammatic representation of a deoxyribonucleic acid molecule made into the form of a ring.  More specifically, it is a representation of Z-DNA, which forms a left-handed helix.  To buy a normal B-DNA representation, as first described by Watson and Crick and having a right-handed helix, go here. I also have a heart version here.

This is a US ring size 6, which is 0.65 inches or 16.5 mm inside diameter; other sizes can be created upon request.

Rough design and photography by Cheri Cloninger.  Detailed design and 3D modeling by James William Kincaid III.

Hi, is there any way this could be inverted? The DNA is spinning the wrong way and I'm a medical animator thinking of getting this for my wife.

The 3D printing enthusiast in me says : "Shiny!" The biochemist in me says : "LEFT HANDED DNA? NOOOO!!!" Unless it is supposed to be z-DNA. In that case cool. But if you want to represent canonic b-DNA, mirror that ring.

Found the conversation that produced this while poking through the forums. It came out really nice, both of you!
