IRAPUATO, MEXICO/BUFFALO, N.Y. — Genes make up about 2 percent of the human genome. The rest consists of a genetic material known as noncoding DNA, and scientists have spent years puzzling over why this material exists in such voluminous quantities.
Now, a new study offers an unexpected insight: The large majority of noncoding DNA, which is abundant in many living things, may not actually be needed for complex life, according to research set to appear in the journal Nature.
The clues lie in the genome of the carnivorous bladderwort plant, Utricularia gibba.
