Textbook Question
Chapter 10, Problem 7U
Why is cytokinesis an important part of cell division?
a. It is responsible for the proper separation of genetic information.
b. It is responsible for the proper separation of the cytoplasmic contents.
c. It triggers the movement of a cell through the cell cycle.
d. It allows cells to halt at checkpoints.

Sometimes a cells "deal with" damaged DNA by just killing off the cell. This special cellular suicide is called apoptosis. Usually, the cell cycle has checkpoints that prevent damaged/mutated cells from proceeding to the next phase, though. When these checkpoints don't work, apoptosis can be used. If apoptosis did NOT occur, how might the damaged DNA impact the rest of the cell cycle?
A. it may not complete the cell cycle correctly
B. new cells containing damaged DNA may be made
C. the cell may enter G0
D. all of the above are options
E. A and B, but not C
F. B and C, but not A
Give two examples of events that can regulate the cell cycle externally.
Progression through the cell cycle is dependent on both extra- and intracellular conditions. Consider the following conditions. Indicate which checkpoint (s) responds to that condition.a. The cell is large enough to divide.b. The DNA is completely copied during S phase.c. The cell is receiving positive cues from neighbors.d. The DNA is damaged.e. The cell has enough energy reserves to divide.f. Are all the sister chromatids correctly attached to spindle microtubules?
