A cell undergoing mitosis! 

Journey of Mitosis (Cell Reproduction): 

1. Interphase: Period of growth and replication of DNA. (90% of cell’s life). 

G1 Phase: Period of regular growth; mitochondria and chloroplasts multiply.  

Synthesis: DNA is replicated (semi-conservative replication).

G2 Phase: Another period of growth in preparation of dividing. 

2. Prophase: Nuclear membrane breaks down, DNA condenses, spindle fibers appear. 

3. Metaphase: Chromosomes align and attached to spindle fibers. 

4. Anaphase: Sister chromatids (DNA) are split apart to either pole of the cell by the pulling of spindle fibers. 

5. Telophase: Nuclear membrane forms around DNA, chromosomes decondense, spindle fibers break down. 

6. Cytokineses: Cytoplasm divides. 

And the new cells start the cell cycle once more! 

A quick and nifty brush up on mitosis.
