Scientists discover master regulator of motor neuron firing

(PhysOrg.com) -- 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, findings at Rockefeller University 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. The findings upturn dogma in the field and further point to the increasingly indisputable role of RNA as the molecule behind biological complexity.
