Draw a cell with 3 chromosomes in anaphase
One difference between a cancer cell and a normal cell is that
cancer cells divide unconrollably
normal cells divide uncontrollably
cancer cells cannot make copies of DNA
normal cells cannot make copies of DNA
________________is a critical point where stop and go signals can regulate the cycle
Metastasis
Checkpoint
Malignant
Benign
What happens when cells undergo uncontrolled division?
Cancer can develop in that part/organ.
Normal growth of body occurs.
Your body will grow rapidly.
Your body size will become bigger and bigger.
Mitosis is a type of cell division in which two cells are formed.
Identical
Similar
Different
Smaller
Defective checkpoints can lead to abnormal growth.
A) What does it mean to be defective?

what is cancer?
the application of biomaterials to improve existing tissues
the result of an improperly regulated cell cycle

Unregulated cell division leads to tumors.
A) Describe what it means to have unregulated cell division
what happens when a proto-oncogene gets stuck on?
cell will immediately stop dividing
cell cycle instantly pauses
cell will not stop going through the cell cycle
cell will undergo apoptosis
what is NOT a way that cancerous cells are different from regular cells?
they have different shapes
they have multiple nuclei
they have less cytoplasm
they go through the cell cycle at the same pace
