UNIT 4 STUDY GUIDE: CELL CYCLE & DIVISION / CANCER / STEM CELLS (CH 10)
Topics / Concepts:
CELL CYCLE and MITOSIS (CH 10)
G1, S, G2 stages of interphase
phases of mitosis and cytokinesis
-prophase; metaphase; anaphase; telophase
control of cell cycle / cancer
cyclins
benign vs. malignant tumor
metastasis
causes of & treatments for cancer
centrioles
spindle fibers
stem cells: totipotent vs. pluripotent vs. multipotent
benefits of stem cell therapy
chromosome structure:
chromatin; sister chromatids; centromere
Review Assignment: to be turned in on the day of the Unit 3 Test!
1) Define:
A) Sexual Reproduction:
B) Asexual Reproduction:
2) Identify / discuss 3 reasons why cell growth is limited.
3) What are chromosomes? What is their role in cell division? Sketch and label a typical chromosome.
4) List and state the main event(s) occurring in the phases of the CELL CYCLE.
Interphase (3 phases):
Events:



After interphase:


5) Name 2 types of proteins that regulate the cell cycle.
6) How are cancer cells different from normal, healthy cells?
&
7) In the space below, draw an animal cell in each phase of mitosis and cytokinesis. Assume the animal cell has 4
chromosomes (2 pairs). Include, where appropriate, centrioles, spindle fibers, nuclear membrane, and nucleolus.
early prophase
late prophase
metaphase
anaphase
telophase
cytokinesis
8) What are some treatments for cancer?
9) What are some ways people might prevent getting cancer?
10) What are stem cells?
11) Compare embryonic stem cells and adult stems cells. In other words, how are they similar and how are they
different?
12) Define the following terms:
Totipotent:
Pluripotent:
Multipotent:
13) What are some potential benefits to stem cell research / therapy?
