- Interphase. Before a dividing cell enters mitosis, it undergoes a period of growth called interphase. About 90 percent of a cell's time in the normal cell cycle may be spent in interphase.
- Prophase. In prophase, the chromatin condenses into discrete chromosomes. The nuclear envelope breaks down and spindles form at opposite poles of the cell.
- Metaphase. In metaphase, the spindle reaches maturity and the chromosomes align at the metaphase plate (a plane that is equally distant from the two spindle poles).
- Anaphase. In anaphase, the paired chromosomes (sister chromatids) separate and begin moving to opposite ends (poles) of the cell. Spindle fibers not connected to chromatids lengthen and elongate the cell.
Jul 29, 2024 · Mitosis is the division of a cell into two daughter cells that are genetically identical to the parent cell. Meiosis is the division of a germ cell into four sex cells (e.g. egg or sperm), each with half the number of chromosomes of the parent cell.

- Mitosis is important to multicellular organisms because it provides new cells for growth and for replacement of worn-out cells, such as skin cells....
M Phase (Mitosis phase): This is where the actual cell division occurs. There are two key steps in this phase, namely cytokinesis and karyokinesis. The interphase further comprises three phases: G0 Phase (Resting Phase): The cell neither divides nor prepares itself for the division.

Today, mitosis is understood to involve five phases, based on the physical state of the chromosomes and spindle. These phases are prophase, prometaphase, metaphase, anaphase, and...
Feb 2, 2023 · Interphase has three stages: G1-phase : The first growth phase of the cell cycle, it is the resting stage during which some cell organelles increase in size, and the cells rapidly synthesize the different types of RNA and proteins.
