Beaded DNA Earrings in Greens

Last night I made a long pair of green DNA Earrings, and today I listed them in the Earrings Section of my Etsy shop. 
With 12 sets of base pairs, these earrings are a bit longer than I typically make. The length of earrings from top of ear wire is 72 mm (almost 2 3/4 inches).
The coloring of the base pairs comes from the enzyme PpiI which is found in the microorganism Pseudomonas putida. Pseudomonas putida is a safe strain of soil bacterium, and is the first patented organism in the world. Because it is a living organism the patent was disputed and brought before the United States Supreme Court in the historic court case Diamond v. Chakrabarty which the inventor, Ananda M. Chakrabarty, won. It demonstrates the ability to biodegrade organic solvents such as oil. The specific base pair sequence shown in each earrings is
GAACN5CTC

I like the way the spirals look from different angles.
 The helices are stiff, but flexible.  They bend from side to side, but they don't untwist.
