Genes are written in DNA and RNA molecules using a code of chemical units called bases. These bases form pairs, which is critical to their function. In DNA, A (adenine) pairs with T (thymine) and G (guanine) pairs with C (cytosine). In RNA, G pairs with C and A pairs with U (uracil).
The charms are based on shapes of the base molecules. They are strung onto a chain at the place where they would normally connect to the sugar-phosphate backbone.
This set of two necklaces comes with your choice of A-T, A-U, or G-C.
The charms are about 3/4 inch long, are made with high-quality reclaimed/recycled sterling silver. You an choose the chain style you would like: 16" silver snake chain (shown), 18" silver snake chain, or your choice length of black cotton cord. If you would like two different style chains, please let me know in the "note to seller" section when you check out. Make sure to tell me which molecule goes on which chain.
These come in a pretty, recycled gift box and include an informational card about the molecules.
