Answer: Protein
Explanation: Molecule Dumont is a protein molecule, with Groucho being a DNA molecule, Chico being the ribosome, and Harpo being the Golgi apparatus.
Groucho (DNA) contains the information needed for the protein to be produced, and sends this information to Chico(ribosome) with a messenger molecule(mRNA). At Chico, the information is processed and the Dumont is synthesized with various of its subunits, called amino acids. Once done, Dumont moves over to Harpo (Golgi apparatus), where it is basically 'packaged', meaning it is modified for either staying in the cell, being sent to fuse with the membrane, or covered in it's own membrane and sent out of the cell.
