Answer:
Mitosis is a method of cell division in which a cell divides and produces identical copies of itself. The primary mechanism by which organisms generate new cells is through cell division
Explanation:
Prophase: The duplicated chromosomes are compacted and can be easily visualized as sister chromatids. The mitotic spindle, a network of protein filaments, emerges from structures called centrioles, positioned at either end of the cell. The mitotic spindle is flexible and is made of microtubules, which are in turn made of the protein subunit, tubulin.
Metaphase: The nuclear membrane dissolves and the mitotic spindle latches on to the sister chromatids at the centromere. The mitotic spindle can now move the chromosomes around in the cell. "You can make an analogy to a girder that's holding up a skyscraper," said Hoyt. "Except the girder can assemble and disassemble very rapidly. They are structural elements that are extremely dynamic." By the end of metaphase, all the chromosomes are aligned in the middle of the cell.
Anaphase: The mitotic spindle contracts and pulls the sister chromatids apart. They begin to move to opposite ends of the cell.
Telophase: The chromosomes reach either end of the cell. The nuclear membrane forms again and the cell body splits into two (cytokinesis).
At the end of mitosis, one cell produces two genetically identical daughter cells.
