Question
Select the incorrect statement.
- The first part of the mitotic stage is called karyokinesis.
- The second part is called cytokinesis.
- Mitosis is useful to remove damaged cells.
- During telophase, the sister chromatids are arranged in the center of the cell.
Hint:
Mitosis is responsible for a healthy growth of an organism producing two identical daughter cells as the parent cells.
The correct answer is: During telophase, the sister chromatids are arranged in the center of the cell.
- Mitosis is responsible for growth as the number of cells double
- Mitosis also helps in replacing the damaged and dead cells with new cells
- Mitosis involves karyokinesis as the first step: division of nuclear contents
- The second step will be cytokinesis which is the division of the parent cell cytoplasm into daughter cells
- During metaphase, the sister chromatids are arranged at the equator of the cell
- During telophase, the spindle fibers contract and the sister chromatids are pulled to the opposite poles
