Calculate the mitotic index for each tissue using the following equation: Number of cells dividing: total number of cells (ex. 1:13 one cell in metaphase and 12 in interphase for a total of 13 cells.) Remember: only the cells in Interphase are not actively dividing. 7. When studying cell division in tissue samples, scientists often calculate a mitotic index, which is the ratio of dividing cells (those NOT in interphase) to the total number of cells in the sample. Which type of tissue would have a higher mitotic index, normal tissue or cancerous tissue? Explain and use evidence from the data you collected.
