WebInterphase (cell growth) Mitotic phase (cell division) is the period of a cell’s life when it carries out its normal growth and metabolic activities. It is also the time during which a cell undergoes a closely ordered sequence of activities in preparation for cell division. Interphase is made up of 3 sub-phases. Web31 mrt. 2024 · NCI Dictionary of Cancer Terms. To find the mitotic rate, the number of cells dividing in a certain amount of cancer tissue is counted. Mitotic rate is used to help find the stage of melanoma (a type of skin cancer) and other types of cancer. Higher mitotic rates are linked with lower survival rates.
The mitotic index is a measure of cellular proliferation. It is defined as the percentage of cells undergoing mitosis in a given population of cells. Mitosis is the division of somatic cells into two daughter cells. Durations of the cell cycle and mitosis vary in different cell types.
