<< DNA content of our genomes resembles a complex biological language, composed of coding regions and regulatory regions. Although protein-coding regions in DNA could be compared to a traffic signal – utilizing a simple stop or go message – the regulatory regions in DNA are more like poetry. “The regulatory sites in DNA operate like a light switch to turn a gene on and off. In animals, it’s extremely complex,” said David Arnosti (..) “There might be hundreds of protein factors in the cell that bind to the gene and impact activity. And there might be hundreds of binding places.” He compares the “language” used in these regulatory sites to poetry. “It may be Emily Dickinson, or Shakespeare or Allen Ginsberg; but all are using ‘words’ to evoke thoughts and emotions, to control the message” >>
