Experiment Illustration (image) Canadian Institute for Advanced Research Share Print E-Mail Caption The image represents a fly (front view), the fly brain is outlined in the head, and the 'string of beads' that is spiraling out of it is a string of DNA wrapped around histones (the proteins that can regulate DNA by being epigenetically modified). In front of the fly is a blue sugar drop, the food we use in our feeding behavior experiments. Briefly, the fly represents the animal, the DNA/histones represent DNA and epigenetic regulation, and the drop represents feeding behavior.
