I am not sure that I understand your question. You want to know if
mitosis has occured after the fact, as in, this cell divided yesterday or
several days ago? If that is your question, the answer is no. The only way
to see mitosis is to catch the cell in the act, not easy to do.
    You can see incorporation of DNA analogues such as thymidine or
bromodeoxyuridine with autoradiography or immuno, but you must give a
compound to label the cells before they start to synthesize DNA.
