interphase prophase metaphase anaphase telophase cytokinesis
 
2. 
what are the parts of a chromosome structure?
 
SISTER CHROMATIDS CCENTROMERE
 
3. 
Chromosomes are made of ??? how many per person? when visible? replicated...???
 
DNA 46 cell division before cell division
 
4. 
Mitosis: phases??
 
P M A T
 
5. 
Prophase
 
1st & longest(mitosis); chromosomes visible; centrioles=opposite side, form spindles;nuclear envelope breaks down; nucleolus disappears
 
6. 
Metaphase
 
shortest; chromosomes line up in middle of cell and spindle fibers attach
 
7. 
anaphase
 
centromeres split sisters move away
 
8. 
Telophase
 
chromosomes become dense and are yarn like nuclear envelope reforms & nucleolus reappears; spindle breaks apart mitosis is complete
 
9. 
cytokinesis
 
division of cytoplasm cleavage or furrow forms; plant: cell plate is formed
