Mitosis
2
1.Prophase

• Chromosomes coil to short fat rods

Nuclear envelope breaks up
Spindle fibers assemble across cell
Plant Cell Prophase
Animal Cell Prophase
3
a. Early Prophase

• 1. Chromatin coils to chromosomes

2. Nucleolus nuclear membrane break down
disappear
3. Centrioles move to poles (animal cells only).
4
b. Middle Prophase

• Spindle fibers (microtubules)
• appear

2 Kinds Polar centriole to centriole Kinetoch
ore centromere to centriole
Control Movement
5
c. Late Prophase

• Aster appear (fibers that radiate from each
  centriole)

6
2.Metaphase

• Kinetochore fibers move chromosomes to equator
  cell line up.

7
3.Anaphase

• Centromere splits
• Sister chromatids pulled to opposite ends

8
4.Telophase

• Identical chromatids at opposite end (each side
  has complete set of chromosomes)

Centrioles spindle disappear
Chromatids unwind elongate to chromatin
Nucleolus nuclear membrane reappear
