New research shows that a tiny piece of RNA has an essential role in ensuring that embryonic tissue segments form properly. The study, conducted in chicken embryos, determined that this piece of RNA regulates cyclical gene activity that defines the timing of the formation of tissue segments that later become muscle and vertebrae.
