Cells often need to turn on a set of genes together to activate a metabolic pathway that is needed – for example, to be able to break down lactose when glucose isn’t available, or synthesize a needed amino acid. How do prokaryotes (such as bacteria) typically express a set of genes together? [a] How do eukaryotes (such as humans) typically express a set of genes together? [b]

Extra credit (2 pts if answered correctly – I will add the points to your score) In eukaryotes (such as humans), two individuals can be born that are genetically identical, but they can end up with slightly different phenotypes from each other. How does epigenetics explain this?
