Interphase
G1: Growth of cell
S: Replication of DNA (46 chromosomes -> 92 chromosomes)
G2: Preparation for mitosis (replicate other organelles)

Prophase
DNA (chromatin) condenses (coils) into chromosomes.
Nuclear envelope/nuclear membrane disappears
Centrioles move to opposite ends of the cell

Metaphase
Chromosomes line up on the equatorial plate (middle of the cell)
Mitotic spindle forms Centrioles and microtubules

Metaphase

Anaphase
Chromosomes are pulled apart at the centromere by the microtubules attached to the centrioles in the mitotic spindle.

Telophase
Chromosomes are at opposite ends of the cell
Two nuclear envelopes reform around each 46 set of chromosomes
Chromosomes uncoil and the DNA is now called chromatin

Cytokinesis
Division of the cytoplasm.
TWO new IDENTICAL cells are formed.
