Once seen as weak partner of DNA, gene helps control cells' activity
(NEWSER) - RNA has long been seen as DNA’s little brother, a messenger between the human genome and cells’ protein factories. But studies point to a bigger role—ribonucleic acid can “turn off” certain genes, for example, fighting a range of health problems, the New York Times reports. “This is potentially the biggest change in our understanding of biology since the discovery of the double helix,” says a biologist.
