Mechanistic and morphological differences between cell division processes in a prokaryotic (E. coli or B. subtilis) and eukaryotic cells: b animal cells, c Budding yeast and d Fission yeast. A microtubule-based apparatus called the mitotic spindle conducts genome segregation during eukaryotic cell division. Bacterial cells (with some exceptions (Ptacin et al. 2010)) do not have mitotic spindle. While in fission and budding yeasts nuclear envelopes remain intact, the envelopes in animal cells break down during mitosis (open mitosis)
