So, I made a few pairs of beaded DNA earrings, making yet more modifications to Gwen's fabulous pattern.
major and minor grooves that I used for the necklace, since it takes about 20 base pairs to see the grooves well, and it's difficult to appreciate them in a 10-bp pair of earrings. Instead, for these earrings, I adjusted the sizes of the seed beads in the backbone to make it narrower, and I used 11° seed beads for the bases. I used two seed beads each for the purines, A and G, and one seed bead for the pyrimidines, C and T, since purines are bigger than pyrimidines.
5' cap made of a specially modified G nucleotide, which serves to both stabilize the molecule (since RNA is much less stable than DNA), and to direct it to the ribosomes where it is read to make proteins. However, in these beaded DNA renditions, I must admit that I added the caps for purely aesthetic reasons.
I like how these earrings turned out, although I didn't get them to work without several attempts. To give you an idea, here are several of its prototypes:
