PRE-LAB QUESTIONS
1. What are chromosomes made of?
Chromosomes are made up of a material called, chromatin. Chromatin is made up protein and
DNA.
2. Research the differences between mitosis and binary fission. Identify at least one difference and
explain why it is significant.
Mitosis occurs id eukaryotes, while binary fission takes place in prokaryotes. Binary fission is a
m
er as
faster way for cell division since in way it is cut in half. Therefore, it would be more efficient than
co
mitosis. While mitosis is most important for cell growth and generation. Mitosis involve several
eH w
o.
cell divisions phases like prophase, prometaphase, metaphase, anaphase, and telophase.

3. Cancer is a disease related to uncontrolled cell division. Investigate two known causes for these
rapidly dividing cells and use this knowledge to invent a drug that would inhibit the growth of
o
aC s
cancer cells.
vi y re
Cell cycle regulators could be one solution to control or manipulate the cell cycle. Cell regulator
ed d
could encourage cell division or restrict in favorable conditions. Moreover, attempting to
ar stu
manipulate the processes of phases by controlling the cell division factors before initiating to
stop cells to over grow. Furthermore, A second approach could be to interfere in important
is
Th
parts in the G2 and M. If there could be a drug to be able to interfere during this specific process
could prevent an uncontrollable cancer.

Result Tables
Table 1: Mitosis Predictions
I believe each stage of mitosis in a plant cell will take
Predictions
up to four hours.
The cell cycle of a plant cell takes 24 hours and there
Supporting Evidence are 6 stages, therefore I divided both numbers to get
the outcome the hours per stage.
