Mitosis with Diagram in English and Urdu


The Process of Cell Division Mitosis  with Diag


Prophase

  • Nucleolus disappears
  • Chromosomes condense.
  • Mitotic spindle appears.
  • (Nuclear membrane fragments).
  • (Microtubules of spindle attach to centromere of chromosome).

Metaphase

  • Chromosomes align along metaphase plate.

Anaphase

  • Chromosomes divide, pulled by the spindle.
  • Sister chromatids move apart at about 1 µm/sec
  • Cell elongates as other microtubules push poles of cell apart.

 

Telophase

  • Chromosomes uncoil.
  • Nucleolus reappears
  • Nuclear membrane reappears.
 this organism will have some trouble during meiosis.
