Mitotic cell division is divided in Prophase, Metaphase, Anaphase and Telophase.

Explanation:

  • As a cell enters metaphase from prophase, nuclear membrane disappears.
  • Chromosomes are tightly coiled and each chromosome is now made of two chromatids, attached at centromere.
  • Spindle apparatus is fully formed during metaphase, made of spindle fibres.
  • And as the cell proceeds in metaphse, the chromosomes start arranging themselves on equatorial region of cell.
  • Centromeric region of chromosome attaches to spindle fibre, the attachment is mediated by a protein entity, termed khinetochore.
  • In the final stage of metaphase, the chromosomes are linearly arranged on so called metaphase plate. Metaphase plate lies perpendicular to spindle apparatus.
