Caption: Activity pattern of one of nearly 5000 potential genetic switches (enhancers) identified by Visel et al. This particular switch is located on human chromosome 5 and turns on genes in developing mammalian limbs, as shown here by reporter gene staining (dark blue) in a transgenic mouse embryo.
