Stages Of Mitosis
The stages of mitosis are quick processes that occurs in eukaryotic cells that are membrane bound structures and organelles. Genetically identical daughter cells are produced from mitosis. Stages of mitosis are interphase, prophase, metaphase, anaphase and telophase.
- Interphase Energy is gathered in the cell with metabolic activity to prepare for the stages of mitosis. The nucleus is visible with more than one nucleoli inside, two centrosomes and loose chromatin fibers.
- Prophase The nucleoli in the nucleus are not visible and will not reappear until later stages of mitosis. The chromatin fibers coil tightly to condense into chromosomes, then join in pairs at the centromere. Spindle fibers made of microtubles begin to form in the cytoplasm. The growing spindle fibers push the centrosomes away from each other.
- Metaphase The nuclear membrane disappears. Cenetromes divide to opposite ends of the cell poles and they align with one another. The chromosomes line up at the metaphase plate, which is an area between the cell poles and the chromatids of the chromosomes attach to the microtubules. A spindle is formed from this attachment.
- Anaphase Chromosomes separate and move to opposite cell poles by kinetochore movement in the microtubles. The cell poles move further apart until they have a complete set of chromosomes.
- Telophase During the last step of the stages of mitosis, daughter nuclei form at the cell poles as the microtubules become longer. The chromatin uncoil, the nucleoli appear again and nuclear envelopes are formed. The nucleus has divided into two identical nuclei; the stages of mitosis are completed.
