Carnivorous plant throws out 'junk' DNA

The newly sequenced genome of the carnivorous bladderwort plant provides surprising insight into noncoding 'junk' DNA, a mysterious genetic material that makes up about 98 percent of the human genome and much of the genomes of other species. The bladderwort genome has almost no junk: 97 percent consists of genes and small control regions, showing that vast quantities of noncoding 'junk' DNA are not needed for complex life to exist.
