All organisms must regulate gene expression by turning genes on and off different cells at different times. In prokaryotic cells, related genes may be organized into operons , which can be turned on and off as a single unit. Eukaryotes have more complex modes of control, including the packing of chromosomes, RNA slicing (which can […]
