MITOSIS
Division of the nucleus
4 phases

INTERPHASE

Grows
DNA replicates
Prepares to divide
90% of the cells life

PROPHASE
Nu clear membrane despairs
Spindale fibers appear
You can see the duplicated chromosomes

ANAPHASE
Sister chromatids move to opposite ends

TELOPHASE
Nuclear membrane reappears
Chromosomes loosen up

CYTOKINESIS
Division of cytoplasm
Always moving to the next stage

TABLE
Phases What it does
Interphase Prepares to divide, and DNA replicates
Prophase Nucleus disappears, and spindle fibers appears
Metaphase Chromosomes move to the middle
Anaphase Sister chromatids move to the middle of the cell
Telophase Nuclear membrane reaper, chromosomes loosen up
cytokinesis Division of cytoplasm
