Canadian poet Christian Bök wants his work to live on after he’s gone. Like, billions of years after. He’s going to encode it directly into the DNA of the hardy bacteria Deinococcus radiodurans. If it works, his poem could outlast the human race. But it’s a tricky procedure, and Bök is doing what he can to make it even trickier. He wants to inject the DNA with a string of nucleotides that form a comprehensible poem, and he also wants the protein that the cell produces in response to form a second comprehensible poem. Here’s a peek at the hellish task this DNA Dante has condemned himself to.
