- Well, the centriole is not present in the Pro-cariotic cell, nor is it in the permanent cell. So even if Amitosis can occur in procariotic cells, why not Amitosis occur in permanent cells? What is the thing that does not allow the permanent cell to divide normally in Amitosis like procariotic cell?Most medically useful antibiotics interfere with either peptidoglycan synthesis or ribosome function. Why would the cell membrane be a poor target for antimicrobial medication?One of the early results shows that the post-centrifugation pellet of encapsulated cells also contains EA1 and/or Sap. Why is this not proof that Bacillus anthracis cells have both an S-layer and a capsule simultaneously?
