The nucleobases

<jats:title>Abstract</jats:title> <jats:p>‘The Nucleobases’ is a modular, acrostic poem, written according to a burdensome constraint, in which the molecular structure of the nucleotides in DNA determines not only the selected lexicons (which, in this case, consist only of nine-letter words), but also their arrangement in the line. Each poem maps out a molecule, while conveying a pastoral sentence about the bees (doing so in honour of Virgil, the first of all poets to have a line of poetry enciphered into the genome of an organism...).</jats:p>
