Mitosis stages

Interphase

Group of stages in the cell cycle where the cell grows, duplicates its DNA, and prepares for mitosis.

Prophase

• After the DNA replicated, the two copies are joint together at centromere ​

• Double diploid number (4n)​

• X-shaped chromosomes appear​

• Nuclear membrane disappears​

• Spindle fibers form ​

​

Metaphase

• Chromosomes lined up along the equator of the cell​

• Spindle fibres extend from the poles of the cell to the chromosomes ​

Anaphase

• The chromosomes separate to become two independent chromatids ​

• Spindle fibers contract and pulling the chromatids to opposite poles ​

Telophase

• A new nuclear membrane encloses the chromosomes at each pole​

• The chromosomes uncoil and are no longer visible as individual strands​

Cytokinesis

• Division of the nucleus is complete​

• The cytoplasm then divides, and the result is two identical daughter cells​
