Question

Can you brief the sequence of events occurring during mitosis?

Answer 1

Mitosis

1. Mitosis is a part of the cell cycle that occurs in the M phase of a cell cycle.
2. Where newly formed DNA is separated and makes two cells, each cell contains one chromosome of the parent cell.
3. Mitosis occurs in 4 phases- Prophase, Metaphase, Anaphase, and Telophase.
4. Prophase: The chromatin fibres are tightly coiled, and Kinetochore assembles at the centromere, each duplicated chromosome appears as two identical sister chromatids joined together. The nucleoli disintigrate. The mitotic spindle starts forming.
5. Metaphase: The microtubules start to exert force on the chromosomes that the chromosome ends up in the middle of the cell. This is the metaphase plate. Each cell gets a whole functioning genome.
6. Anaphase: The dividing of the sister chromatids marks the onset of anaphase. The daughter's nuclei have these chromatid sisters as a chromosome. This Chromosome comes towards the pole by fibres that are present in each kinetochore of the chromosome. At the end of anaphase, the two ends of the cell have an equal complete collection of chromosomes.
7. Telophase: In this phase, two daughter nuclei become to form a cell. The nuclear membrane starts forming around other cell organelles starts to appear. Telophase follows the cytokines phase which denotes the cytoplasm division and makes two daughter cells.
