Gene Regulation It’s all about the switches!
Questions Abound • If all eukaryotic cells have the same DNA, why are there different types of cells in the same multi-cellular organism? • Do all genes make proteins? • Do all genes get “read”? Bacteria can enlighten us. . . . .
Prokaryotes vs Eukaryotes Gene Regulation in both is similar but there are differences. In eukaryotic cells: • No operons • Individual genes controlled • Regulation is more complex
What do eukaryotic genes do? • Maintain Homeostasis via cell signaling (e.g. hormones) • Drive Cellular Differentiation • Forming different cell types • Creating different subcellular structures
