I've featured DNA inspired jewelry before which used different techniques.  Beadweaving is perhaps the best way to showcase the double helix which comprises of two spiral backbones made of sugar and phosphate groups. These are linked by rungs of 4 types of nucleotides. These are called base pairs because adenine from one ladder will only bind to thymine of the other, while guanine will do so with cytosine.

Bugles are the base pairs

Gwen Fisher (GwenBeads), a beader and a mathematician whose beadwork I featured before, came up with inspirational designs and a detailed video tutorial on how to get that spiral effect right using ladder and peyote stitches.  I also love how she used a bit of coding from an actual bacterial species to guide her with the seed bead colors.

Her first blog post covers the details.  The closeup of the earrings above shows bugle beads representing the base pairs (rungs).  So to show greater scientific accuracy, she wrote a second post and described how she substituted the bugles for the color coded seed beads representing the base pairs.

Gwen is also one half of Beadinfinitum where she sells finished beadwork, tutorials and kits.
