Light Micrograph of Utricularia gibba (image) University at Buffalo Caption This is the light micrograph of the bladder of the carnivorous bladderwort plant, Utricularia gibba. A new study finds that U. gibba has a remarkable genome for a complex organism. Just 3 percent of U. gibba 's tiny genome is made from so-called "junk DNA," compared with about 98 percent of the human genome. The finding contradicts the notion that vast quantities of noncoding junk DNA are crucial for complex life.
