Q

How are tumor suppressor genes and proto-oncogenes play a role in the cell cycle?

Q

how can a cancerous cell invade the immune system?

A

Cancer cells do not possess the identifying proteins on their surface which allows them to not be recognized in the immune system.

Q

compare and contrast normal and cancer cells

A
  • Normal cells stay in one place will cancer cells can travel all over
  • normal cells have a predetermined life, and cancer cells can liver forever
  • normal cells have a job they need to do while cancer cells are not functional
17
Q

What are chromosomes made of?

A

DNA

18
Q

What is cancer

A

Cell division is out of control.

19
Q

Be able to differentiate between plant and animal cell cytokinesis.

A

Animal cell has a cleavage furrow and splits into 2
Plant cell has a cell plate and cuts vertically

20
Q

How do checkpoints help regulate cell division?

A

G1– Makes sure the cell has enough nurturance for the next cell division
M — All chromosomes attach to spindle fibers
S – When DNA is copied with no errors

21
Q

Describe apoptosis and why it is needed/important.

A

Apoptosis is programmed cell death. to rid the body of cells that have been damaged beyond repair.

22
Q

What would happen if the spindle fibers were damaged?

A

The cell wouldn’t go through anaphase and then the chromosomes wouldn’t separate properly.

23
Q

Cancer cells can be described as____and_____

A

benign___ (good) and _malignant____ (bad).
