Role discovered for 'junk' DNA
Non-coding regions of DNA have often been called 'junk' DNA, because they don't behave like genes, nor even resemble genes in many instances. Nonetheless, scientists have long suspected that they somehow play an important role because transcription still occurs in those regions, just as if they were genes. Now, biologists at Washington University in St. Louis have found that two plant-specific RNA polymerases work together to use the non-coding region of DNA to prevent destructive, virus-derived genes from being activated.  More†
