Explanation:

• Mitosis is a type of cell division in which somatic cells divide and duplicate.
• It takes around 1 hour for the process of mitosis to complete.
• It has five phases: Interphase, Prophase, Metaphase, Anaphase, Telophase, and Diakinesis.
• In case of the metaphase, mitotic spindle starts to form as the chromosomes lie on the metaphase plate.
• In Anaphase, the spindle fibers contract and pull apart the chromatids to their respective poles.
• The spindle fibers formed are elastic in nature.
