Mitosis Flashcards
Division of nucleus
Mitosis
Also known as karyokinesis
Mitosis
Result in a division of the cell nucleus and is divided into a series of phases
Mitosis
Phases of mitosis
- Prophase
- Prometaphase
- Metaphase
- Anaphase
- Telophase
Start of mitosis
Prophase
First phase
Prophase
Breakdown of nuclear membrane. Spindle fiber appears. Chromosomes condense. Nucleolus disappear.
Prophase
The first change phase
Prometaphase
Spindle fibers attach to chromosomes. Chromosomes condense. Sister chromatids develops a protein structure
Prometaphase
Protein structure
Kinetochore
Microtubules that do not engage the chromosomes
Polar Microtubules
Chromosomes at the center
Metaphase
Change phase
Metaphase
Chromosomes align
Metaphase
Chromatids to opposite poles
Anaphase
Awkward phase
Anaphase
Cells become visibly elongated (oval shape). Centromeres divide. Sister chromatids move to opposite poles
Anaphase
Reformation of nuclei
Telophase
Distance phase
Telophase
Nuclear membrane reforms. Chromosomes decondense. Spindle fibers disappear. Nuclear envelope forms around the chromosomes.
Telophase
Cell motion
Cytokinesis
Cytoplasm divides. Parent cell becomes two daughter cells with identical genetic information
Cytokinesis
Fissure in animal cells
Cleavage furrow
The middle structure in plant cells
Cell plate
