proto-oncogenes
tumor suppressor genes
Decide if the following description matches a proto-oncogenes or tumor suppressor genes.
requires mutation in only one allele to cause cancer
proto-oncogenes
tumor suppressor genes
Decide if the following description matches a proto-oncogenes or tumor suppressor genes.
mutation in allele is a dominant trait
proto-oncogenes
tumor suppressor genes
Decide if the following description matches a proto-oncogenes or tumor suppressor genes.
mutation in allele is a recessive trait
proto-oncogenes
tumor suppressor genes
Decide if the following description matches a proto-oncogenes or tumor suppressor genes.
functions like a gas pedal in car
proto-oncogenes
tumor suppressor genes
Decide if the following description matches a proto-oncogenes or tumor suppressor genes.

proto-oncogenes
tumor suppressor genes
Cancer is
hyperactive metabolism
uncontrolled cell division
uncontrolled cell death
specialization of cells for a particular job
This term means "programmed cell death". It is when a cell is "told" to die, rather than death by disease or wearing out.
senescence
apoptosis
planned obsolescence
die, just die, darn you liver cell!
This is a gene that could cause cancer, but needs some sort of alteration or mutation to do so.
oncogene
proto-oncogene
tumor suppressor gene
Gene Kelly
A gene that protects a cell from becoming cancerous.
oncogene
proto-oncogene
tumor suppressor gene
apoptosis
Which of these is NOT a sign of cancer cells?
Consistent and widespread apoptosis
Loss of specialized features such as large fat bodies
Variety of sizes and shapes in the same cell types
Larger nucleus, smaller amount of cytoplasm
What features would you look for in a cancer cell?
Larger or irregularly shaped nucleus
Loss of features such as flat, square shapes and protrusions that the cell type should have
Lack of well-arranged cells; positions are random with a variety of sizes
All of these are indications of cancer
Programmed cell death is known as
metastasis
angiogenesis
malignant
apoptosis
Recruitment of blood vessel by a tumor is referred to as
metastasis
apoptosis
angiogenesis
benigh
Process by which cancer cells have migrated to another location in the body is called
apoptosis
malignant
genetic flow
metastasis
Which of the following is NOT a way in which a proto-oncogene can be converted into an oncogene?
mutation that results in a degradation-resistant protein
translocation of a proto-oncogene to a more active promotor region.
duplication of gene within the genome.
mutation that results in a protein that has lost its function
Cancer in supporting tissue such as bone or muscle is referred to as
carcinoma
sarcoma
lymphoma
leukemia
Cancer of the blood due to cells in bone marrow divided out of control is referred to as
carcinoma
sarcoma
lymphoma
leukemia
In normal tissue, the
rate of mitosis is equal to the rate of apoptosis
rate of mitosis is much greater than the rate of apoptosis
rate of mitosis is less than the rate of apoptosis
rate of mitosis and apoptosis will be zero
