To calculate the mitotic index, you count the number of cells undergoing mitosis in a given sample and divide this number by the total number of cells in the sample. The result is usually expressed as a percentage. Mitotic index is commonly used to assess the rate of cell division in tissues, especially in cancer research.
Cancer cells have higher mitotic index because they have a mutation in the DNA so they reproduce uncontrollably and therefore divide faster which means they have a higher mitotic index. ex. In a normal lung tissue, % of cells dividing is 5% while in a cancerous lung the % of cells divding is 25 %
No, not all cells in an adult can undergo mitotic division at any given time. Some cells, like muscle and nerve cells, are in a non-dividing state (G0 phase) and remain that way for extended periods. Others, like skin and blood cells, continuously undergo mitotic division to replenish and repair tissues.

Mitotic cell division enables growth, tissue repair, and asexual reproduction in multicellular organisms. It ensures that daughter cells receive an exact copy of the genetic material from the parent cell, maintaining genetic stability. Additionally, mitosis plays a crucial role in the development and maintenance of an organism's tissues and organs.
1.) fertilization of egg by sperm 2.) mitotic cell division of zygote 3.) differentiation of cells into tissues 4.) organ development
A mitotic lesion is one in which there is an increased rate of mitosis in cells. This can be indicative of cancer where there is abnormal proliferation of cells.

A mitotic lesion is an abnormality in a cell that affects its ability to divide properly during mitosis. This can lead to errors in chromosome segregation and potentially result in genetic mutations or cell death. Mitotic lesions are associated with conditions such as cancer and developmental disorders.
Cancer cells have higher mitotic index because they have a mutation in the DNA so they reproduce uncontrollably and therefore divide faster which means they have a higher mitotic index. ex. In a normal lung tissue, % of cells dividing is 5% while in a cancerous lung the % of cells divding is 25 %
Somatic cells are produced from mitosis. Gametes are produced from meiosis.
It still needs cells to form the organism. If cells aren't present, tissues won't be formed organs won't form to make organ systems and make organisms. THE CELL CYCLE cells-->tissues -->organs-->organ system-->organism
Because cancer is uncontrolled mitosis of cells; thus if the mitotic index of the breast cells in question is outside the normal range (above it, generally), then this would suggest increased rate of cell proliferation which could indicate cancer.
