The cytoplasm actually divides to produce 2 daughter cells.

What are the 3 stages of Interphase?
Gap1, Synthesis, Gap2
100
Name the 4 stages of mitosis
Prophase, Metaphase, Anaphase, Telophase

What people are at higher risk of contracting Cancer?
Anyone with a direct family relation to someone who has or had been diagnosed with cancer (mostly genetic cancers such as breast or colon)
And
People who are often exposed to everyday carinogens (truck drivers)
200
the area the indentation that is going to form in an animal cell is called the _______ ______
Cleavage furrow
200
Which event occurs during interphase?
a. The cell grows
b. Centrioles appear
c. Spindle fibers begin to form
d. Centromeres divide
A - cell grows is the event occured during interphase
During Interpahse the cell grows larger. That is its size grows about twice and ready to divide.
200
Each chromosomes consists of 2 ____
Chromatids
300
How is cancer classified?
Cancer is a name for over 200 diseases and is classified by uncontrolled cell growth and cell division
300
What does a cell do after it completes telophase and cytokinesis?
Begin Interphase again
300
True or false chromosomes present in cells during interphase?
True. Chromosomes are a result of copied chromatids and appear after the Synthesis phase.
300
During which phase to chromosomes become visible under a microscope?
Prophase
400
Cancer is a result of _______
uncontrolled cell division
400
What role do vesicles play in cytokenisis in plants
Vesicals are responsible to drop off cell wall material that later fuses up together to create the new cell wall.
400
What would happen if the S phase was eliminated?
If the S phase were eliminated, daughter cells would only have half of the DNA required to function.
400
What structure is responsible for moving chromosomes during mitosis?
Spindle fibres
500
What is metastasis?
When cells break away from the original (primary) tumor and moves to another area and uncontrollably cell division occurs (secondary).
500
How does cytokenisis in plant cells differ from cytokenisis in animal cells?
Plant cells cant have 2 proteins that squeeze together the cell like a animal cell because of the cell wall.
500
What is the G0 phase? Give an example of a cell that stays in it permanently.
G0 is a resting phase in which cells aren't preparing to divide. Heart and or nerve cells stay there permanently.

During mitosis, the sister chromatids are separated and pulled to opposite poles during which stage of mitosis?
