Molecular 'Switches' of Gene Expression in the Ciona Notochord (IMAGE)
Caption
Commonly used electrical switches (background, left) are compared to the molecular switches (cis-regulatory modules, or CRMs) identified in this study (background, right). The horizontal bars represent the 14 CRMs identified in this study, and the colored geometric shapes depict binding sites for transcription factors that are required for these molecular switches to function. The image in the center shows a Ciona embryo, with the notochord highlighted in red.
