*Summarize what happens in cell division, according to the song: (0-0:44)
________________________________________________________________________
*In the first stage of the cell cycle, the cell grows, matures, and makes copies of its DNA
in order to prepare to split into two? This is called _____________________________.
(0:45-1:00)
*In Mitosis, there are four stages often abbreviated as PMAT. What do the P, M, A and
T stand for? (1:01-1:13)
P:_________________M:_________________A:________________T:_______________
*In which of these four stages do chromosomes become visible, spindle fibers form, and
the nuclear membrane breaks down?_________________________________________
This is the first stage of Mitosis. (1:14-1:30)
*In the second stage of Mitosis, called ___________________________, chromosomes
line up in the middle of the cell and spindle fibers attach to the centromeres. (2:15-2:29)
*In the third stage of mitosis, _____________________________, the centromeres
break apart and the spindle fibers pull the chromosome pieces (chromatids) to opposite
ends of the cell. (2:30-2:45)
*In__________________________, the fourth and final stage of mitosis, chromosomes
unwind and new nuclear membranes begin to form in each new cell. (2:59-3:13)
*At the end of telophase, the cytoplasm divides and the cell membrane pinches into
two, forming two new daughter cells that exactly alike. This stage is referred to as:
________________________________.(3:14-3:29) This is the last stage of the cell cycle.

Cell division is required for organisms to ___________, mature and maintain tissues. (0:11-0:19)
For many eukaryotic cells, a cell is duplicated every ____hours. Most of the life of a cell is spent
in ________________________.The three stages are: _____ _____ _____ (1:30-1:44)
What do the G1, S, and G2 stages stand for in Interphase? (1:45-2:17)
G1:__________
S:__________
G2:____________
What important process occurs in the “S” phase of interphase? _________________________
(2:00-2:08)
Sketch what you see at each phase of Mitosis and Cytokinesis. Pause it at 3:04 for Prophase,
3:39 for Metaphase, 3:50 for Anaphase, 4:19 for Telophase, 4:45 for Cytokinesis.
