Excerpt from "thymidine dinucleotide in the commission of a crime", April 07, 2004:
Thymidine dinucleotide is a fragment of DNA - made from just two nucleotides. When rubbed into the skin, these snippets mimic chromosome damage from ultraviolet radiation, inducing cells to repair themselves. In other words, you get a tan. Skin lesions take much longer to develop.
Imagine slathering yourself in the nucleotides of a lost lover, watching the tan develop, allowing someone to damage you so subtly, so close to the surface. Just so you can be safe from something worse.
