Introduction To Mitosis
AP Biology
Phases of Mitosis
Interphase- Not part of Mitosis but the much longer phase before the cell splits.
Prophase- Spindles formed by microtubules.
Metaphase- Centromeres convene along metaphase plate.
Anaphase- Sister Chromatid split and move to opposite sides of the cell.
Telophase- New nuclear envelope is formed using parts of the parent cells nuclear membrane.
Interphase
Interphase
Cell prepares for division. Three stages: G1- Cell Grows. S- Chromosomes replicated. G2- Cell grows and prepares for
division.
Prophase
Prophase
In plant cells only prophase is preceded by Preprophase.
Chromatin condenses into chromosomes.
Spindles begin for form. Motor proteins push Centrosomes
along microtubules to opposite ends of the cell.
Metaphase
Metaphase
Spindles attach to Centromeres and chromosomes convene along Metaphase plate.
Analogous to a Tug of War between people of equal strength.
Anaphase
Anaphase
Proteins that bind sister Chromatid are split.
Sister chromosomes are pulled apart by shortening spindles and move towards their respective centrosomes.
Telophase
Telophase
New nuclear envelope formed from parts of the parent cells nuclear membrane.
Chromosomes are enveloped in new nuclei and are unpacked into chromatin.
Mitosis is now complete.
