This pendant is based on the structure of B-DNA, the most common form of this important molecule. B-DNA is a left-handed helix with 10 to 10.5 base pairs per full turn. The double helix structure possesses a major groove and a minor groove, i.e. the helix is not symmetrical. In B-DNA the major groove is significantly wider than the minor groove. In general, DNA-binding proteins associate with the major groove.
The pendant is 3 cm (1.2 inches ) long below the loop and 8 mm (0.3 inches) wide.
The pendant is 3D printed in solid sterling silver, bronze, brass or 14K gold plated brass (shown) and finished with a sterling silver, gold-plated silver or rose gold-plated silver anchor chain to match.
