DNA bracelet | silver The double helix on the wrist instead of the neck. A 20 mm 925 sterling silver charm holding the same molecule that runs through every cell of the body, attached to a 3.8 mm chain with a Pandora-compatible connector so it can join an existing bracelet or anchor a new one. The Science Behind DNA The four DNA bases (A, T, G, C) pair according to rules that Erwin Chargaff established in 1950: A always pairs with T, and G always pairs with C. That complementarity is what makes accurate replication possible and what Watson and Crick used in 1953 to construct their double helix model. The human genome contains roughly 3.2 billion base pairs across 23 chromosome pairs, encoding around 20,000 protein-coding genes. If the DNA from a single human cell were stretched out, it would extend about two metres. Folded inside a nucleus six micrometres across, that two-metre thread is the engineering problem chromatin biology spends its time on.
