The end of prophase is marked by the beginning of the organization of a group of fibres to form a spindle and the disintegration of the nuclear membrane. The chromosomes, each of which is a double structure consisting of duplicate chromatids, line up along the midline of the cell at metaphase.
What are the 4 phases stages of mitosis?
These phases are prophase, prometaphase, metaphase, anaphase, and telophase.
What happens in each stage of mitosis?
1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope …
Why is mitosis important for life?
Importance of Mitosis in Living Process
Genetic stability– Mitosis helps in the splitting of chromosomes during cell division and generates two new daughter cells. … Growth- Mitosis help in increasing the number of cells in a living organism thereby playing a significant role in the growth of a living organism.
