Few molecules are more interesting than DNA -- except of course RNA. After two decades of research, that "other macromolecule" is no longer considered a mere messenger between glamorous DNA and protein-synthesizing machines. We now know that RNA has been leading a secret life, regulating gene expression and partnering with proteins to form catalytic ribonucleoprotein complexes. Read more
