All Rights Reserved.):The yin and yang symbolize multiple things, including the idea that opposing forces are interdependent and balanced in the natural world. This principle can be observed in the Caenorhabditis elegans germ line, where cell proliferation (green; 5-ethynyl-2′-deoxyuridine) and differentiation (red; METT-10) are interdependent and balanced processes. The chromosome morphologies of individual mitotic and meiotic nuclei are also shown (blue; 4′,6-diamidino-2-phenylindole). (See related article on page 6128.)
