Mitosis. 1.Prophase. Chromosomes coil to short fat rods. Nuclear envelope breaks up. Spindle fibers assemble across cell. Animal Cell Prophase. Plant Cell Prophase. a. Early Prophase. 1. Chromatin coils to chromosomes. 2. Nucleolus & nuclear membrane break down & disappear.
Chromosomescoil to short fat rods
Nuclear envelope breaks up
Spindle fibers assemble across cell
Animal Cell Prophase
Plant Cell Prophase
1. Chromatin coils to chromosomes
2. Nucleolus & nuclear membrane break down & disappear
3. Centrioles move to poles (animal cells only).
Spindle fibers (microtubules)
Identical chromatids at opposite end (each side has complete set of chromosomes)
Centrioles & spindle disappear
Chromatids unwind & elongate to chromatin
Nucleolus & nuclear membrane reappear
