16. Answer:-

Mitotic index is the calculation of undergoing cells to mitotic division with respect to the total number of cells. i.e ( Prophase +Metaphase +Anaphase +Telophase)/N × 100%, where N is the total n number of cells.

When a tissue became cancerous then more number of cells go to unrestricted division, whereas in the case of normal tissue the number of cells undergoing mitotic division is less.

In case of cancerous tissue the checkpoints of the cell can not control the faulty cells to go under division, cells vigorously undergo division in less time, so that the cells became abnormal compare to the normal cells. E.g, if normally 10 cells of normal tissue undergo division then in case of cancer tissue it will be 550 above.
