When the Human Genome Project was complete, DNA bowed out of the limelight and gave way to RNA as a major player in genetic regulation. Now, new findings mirror this ideological shift, revealing that one of the most important physiological events in the body — the wiring of motor neurons and muscles — is regulated at the level of RNA.
