Question

When studying cell division in tissue samples, scientists often calculate a mitotic index, which is the ratio of dividing cells to the total number of cells in the sample. Which type of tissue would have a higher mitotic index, normal tissue or cancerous tissue?

Answer 1

Answer:

Cancerous tissue has high number of mitotic index.

Explanation:

Mitotic index may be defined as the cells that undergoes mitosis by the total number of cells. Mitotic index is different in case of cancerous and normal cells.

Cancerous cells has high ability to divide continuously and requires less nutrient factors. The mitotic index of a cancerous cell is more because the number of dividing cell is more in case of cancerous cell than the normal cells.
