2. Metaphase
3. Anaphase
4. Telophase ]]> 2021-02-16 19:26:46 UTC https://padlet.com/carmentosi/a4ce41batq2shud7/wish/1208432031 carmentosi https://padlet.com/carmentosi/a4ce41batq2shud7/wish/1208440517 - Beginning of mitosis
- cytoskeleton disassembles 
- spindles begin to form
- Chromatin condenses to form chromosomes (sister chromatids) 
- centrioles migrate to opposite ends of the cell
- nuclear envelop breaks down
- nucleus disappears ]]> 2021-02-16 19:28:50 UTC https://padlet.com/carmentosi/a4ce41batq2shud7/wish/1208440517 carmentosi https://padlet.com/carmentosi/a4ce41batq2shud7/wish/1208467741 - Microtubules connect to the kinetochores on each side of the chromosomes
- Chromosomes are moved to the equator of the cell by each spindle from the centrioles 
- chromosomes are lined up on a straight line at the metaphase plate ]]> 2021-02-16 19:35:49 UTC https://padlet.com/carmentosi/a4ce41batq2shud7/wish/1208467741 carmentosi https://padlet.com/carmentosi/a4ce41batq2shud7/wish/1208486898 - Spindles pull the two sister chromatids apart

cleavage furrow forms in the center of the cell
- Nuclear envelop forms around the chromosomes
