Mitosis & the Cell Cycle
Transcript of Mitosis & the Cell Cycle
Four important things that happen in Mitosis:
The nucleus divides
Chromatin organizes into chromatids.
The nuclear membrane falls apart
The nucleus disapears .
The chromosomes line up in the middle
The spindle fibers attach to the centromeres
Mitosis and the Cell Cycle
G1: Growth and replication of organelles
S: Synthesis of DNA
G2: Assembly of spindle begins
The nuclear membrane tears so chromosomes can spread out.
The chromatin organizes itself into chromatids.
The nucleolus disappears.
Spindle Fibers blast out of the centrioles
Cytokinesis is when the cell physically splits into two different parts right after telophase occurs. Also the cytoplasm pinches in and then the cell splits into two and that's how Cytokinesis works.
The chromatids are pulled apart by the spindle fibers.
Two new nuclei start to form, each with the same number of chromatid's
The nuclear membranes regrow
The nucleolus reappears
