to activate the egg to form the offspring. When he went to work with the University of Missouri, his research focused on the structure of the nucleus. After his retirement from Berkeley, he went to work for Stanford University at the Hopkins Marine Station, where he researched the structure and replication of the centrosomal complex and proposed ideas as to how it might function as a regulator of cell structure. Some other research was focused on the cell theory in which he concluded that the eukaryotic cell is a whole unit in which the structure contains the basic needs of living for any unit.
