Summary

Although vertebrates appear symmetrical on the surface, their viscera show pronounced left-right asymmetry. In an illustrated Perspective, Robertson summarizes what has been found to date about the molecular underpinnings of the asymmetry set up during embryogenesis, including a report in this week's issue by Isaac et al. (p. 1301) on the asymmetric expression of the transcription factor cSnR in the chick embryo.
