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.
