I'm assuming you meant "Mitosis."
1. Interphase - The cell is engaged in metabolic activity and performing its prepare for mitosis (the next four phases that lead up to and include nuclear division). Chromosomes are not clearly discerned in the nucleus, although a dark spot called the nucleolus may be visible. The cell may contain a pair of centrioles (or microtubule organizing centers in plants) both of which are organizational sites for microtubules.
2. Prophase - Chromatin in the nucleus begins to condense and becomes visible in the light microscope as chromosomes. The nucleolus disappears. Centrioles begin moving to opposite ends of the cell and fibers extend from the centromeres. Some fibers cross the cell to form the mitotic spindle.
3. Prometaphase - The nuclear membrane dissolves, marking the beginning of prometaphase. Proteins attach to the centromeres creating the kinetochores. Microtubules attach at the kinetochores and the chromosomes begin moving.
4. Metaphase - Spindle fibers align the chromosomes along the middle of the cell nucleus. This line is referred to as the metaphase plate. This organization helps to ensure that in the next phase, when the chromosomes are separated, each new nucleus will receive one copy of each chromosome.
5. Anaphase - The paired chromosomes separate at the kinetochores and move to opposite sides of the cell. Motion results from a combination of kinetochore movement along the spindle microtubules and through the physical interaction of polar microtubules.
6. Telophase - Chromatids arrive at opposite poles of cell, and new membranes form around the daughter nuclei. The chromosomes disperse and are no longer visible under the light microscope. The spindle fibers disperse, and cytokinesis or the partitioning of the cell may also begin during this stage.
7. Cytokinesis -In animal cells, cytokinesis results when a fiber ring composed of a protein called actin around the center of the cell contracts pinching the cell into two daughter cells, each with one nucleus. In plant cells, the rigid wall requires that a cell plate be synthesized between the two daughter cells.
I'm a high school junior that took AP Biology last year. I have this down-pat. So no worries.

∙ 12y agoMitosis consists of four main phases: prophase, metaphase, anaphase, and telophase. During prophase, chromosomes condense and the nuclear envelope breaks down. In metaphase, chromosomes align along the center of the cell. In anaphase, sister chromatids separate and move towards opposite poles. Finally, in telophase, the nuclear envelope reforms and the cell divides.
Gap phases (G1 and G2) allow cells to grow in size, monitor internal and external conditions, and ensure that conditions are suitable for DNA replication and cell division in the subsequent phases (S and M phases) of the cell cycle. These phases also provide time for cells to repair damaged DNA or complete necessary cellular processes before proceeding to the next phase.
The four phases found in the M phase are prophase, metaphase, anaphase, and telophase. These phases involve the condensation of chromosomes, alignment of chromosomes at the metaphase plate, separation of sister chromatids to opposite poles, and formation of two new nuclei.
Yes, the menstrual cycle typically consists of four phases: menstruation, the follicular phase, ovulation, and the luteal phase. Each phase is regulated by hormones and plays a role in preparing the body for possible pregnancy.
The G phase of the cell cycle is split into two sub-phases: the G1 and G2 phases. In between these two phases is the S phase (the synthesis phase). One can say the G phase (or the first of the two G sub-phases) occurs before the S phase.
There are two phases in meiosis: meiosis I and meiosis II. Meiosis I involves the separation of homologous chromosomes, while meiosis II involves the separation of sister chromatids. These phases result in the formation of four haploid daughter cells.
