Troy writes that he got his tattoo “as a post-doctoral fellow studying protein folding. The tattoo is sort of a telescoping view of the contents in a cell (many contents omitted, obviously). This came about from a very vague idea of something I wanted, and the artist (Chris Adamek, Immortal Ink, Clinton, NJ) really ran with it. He has no scientific training but came up with some really amazing artwork. He was so enthusiastic and wanted to know all about what it all meant and how it works. I enjoyed the experience of sitting with him for three days as much as I enjoy the result. The DNA doesn’t code for anything (at least not intentionally).”
