Infographic: Cook Up an Exome-Based Diet

See how scientists designed food with amino acid compositions based on protein-coding regions in the genomes of mice and fruit flies.

DNA-to-Dish Recipe

To generate diets with species-specific proportions of amino acids, first sequence all the protein-coding regions (the exome) from an organism’s genome and determine the precise proportion of each of the 20 encoded amino acids (five of the 20 are shown as colored codons in DNA, with their respective abundances displayed in the bar chart). Next, mix amino acids at this exact ratio with other nutrients (carbohydrates, lipids, and so on) and serve. Animals on this exome-matched diet will grow larger than those on equivalent diets that have discordant amino acid compositions.

    There are countless ways for scientists to say, “I love you.” Naming a slime-mold beetle after your wife (and another after your ex-wife) is, apparently, one of them.
