Web21 jul. 2024 · Geneticists define a clone as any organism that is genetically identical to another. Clones can be replicated in the lab, or can be a pair of identical twins naturally born, for example. As you can see, the definition of cloning covers a lot of territory, and part of that territory includes the process of mitosis. WebUsing these data, one can calculate the mitotic index of a cell population. Mitotic index, which is the percentage of cells undergoing mitosis at any time, is the most common marker used for asynchronous determination of cell cycle length. As demonstrated in Figure 3, the mitotic index increases with serum concentration. RPE1 cells exposed to serum
