What characteristics of a cancer cell differentiates them from
normal cells in terms of functionality? Are the protein receptors
different? Biochemical associated with or released from cancer
cells?
Plant cells are different from animal cells in several ways. All
plant cells have a cell wall during their entire existence. The
cell wall has many different functions in different cell types.
Compare and contrast between the two types of plant cell walls
as to their chemical make up, shape, when they are formed, and
morphological properties. Include all chemical components in the
cell wall we discussed during lecture.
Draw two figures showing how each of these cell walls are...
Cancer is caused by rapid, uncontrolled cell division. Cells
lose normal functions and invade normal surrounding tissues.
Metastasize means to travel to another location. A tumor is named
according to tissue of origin. Cause of cancer can be chemical
physical, and biological. Some biological cancers are caused by
diseases that suppress the immune system (HIV or immunosuppressant
drugs after transplants).
Multiple drugs from different classes affect different stages in
the cell cycle. The combinations allow for lower doses, which
reduce...

Describe the six characteristics that cancer cells acquire, or
lose, as they transform from normal cells. Provide an example for
each characteristic and describe the types of DNA changes that may
occur to cause such protein changes.
QUESTION 21
Describe the function of FOS in normal cells
and cancer cells.
For a complete answer, you will need to include:
A) its mechanism of action, including other proteins it works
with and its downstream targets
B) how its activity is regulated
C) whether it acts as an oncogene or a tumor suppressor and why
inactivation or activation of the gene leads to cancer
QUESTION 22
Signal Transduction:
A) Explain how growth factors, acting through the signal
transduction pathway,...
