Stage 1: Interphase
The cell starts to grow.
The cell’s DNA replicates (exact copy).
The cell prepares to divide.
Fun Fact
The cell spends 90% of its life in this stage.

Mitosis has four phases:
1. Prophase
2. Metaphase
3. Anaphase
4. Telophase

Prophase
The nuclear membrane and the nucleolus disappear
Spindle fibers appear (ropes)
Start to see duplicated chromosomes

Metaphase
The chromosomes duplicate and move to the middle.
It has sister chromatids on either side.

ends.

Telophase
The nuclear membrane and the nucleolus reappear
The chromosomes loosen up and become chromatids

What happens?
Stage 1: Interphase
The cell grows, DNA replicates, & the cell
prepares to divide
