a cell 2n =4 show stages of mitosis in this cell
Dear student.
Mitosis consists of 2 major events: Karyokinesis and Cytokinesis.
Karyokinesis consists of 4 stages: Prophase, Metaphase, Anaphase and Telophase.
1. Prophase: Chromatin condenses to form chromosomes. Initiation of mitotic spindle occurs. Golgi complex, ER, nuclear membrane and nucleolus disintegrate.
2. Metaphase: Chromosomes spread throughout the cytoplasm. Chromosomes contain 2 chromatids attached to each other through the centromere. Mitotic spindle formation is completed. All chromosomes align themselves at equator. Spindle fibers attach to kinetochore.
3. Anaphase: Centromere which holds the chromatids together splits and daughter chromatids are now called chromosomes of future daughter nuclei. Chromosomes move away from equatorial plate.
4. Telophase: Chromosomes reach poles. Mitotic spindle disappears. After reaching poles, chromosomes uncoil. Nucleolus, ER, Golgi bodies and other organelles reappear. Nuclear envelope reappears.
Cytokinesis divides the cytoplasm of the parent cell to form two daughter cells in the process of cell division. The cytokinesis process starts at the end of mitosis or meiosis and split a mitotic or meiotic cell into two.
Here 2n=4, so at the end of mitosis, two identical cell will form having same number of chromosome (2n=4)
Hope this information will clear your doubts about the topic.
