After collecting samples of the material found growing on last month's leftovers at the back of your fridge, you realize that you have discovered a new type of organism. you find that the cells have distinct subunits within. further, several of these subunits, which you have nicknamed groucho, chico, and harpo, seem to be involved in the production and transfer of certain molecules. molecule dumont, as you call it, appears after a messenger molecule is sent from groucho to chico. dumont then travels to harpo, where it is covered in membrane and (eventually) released from the cell. dumont is most likely what type of molecule?
