BIOD 210 Module 7 Exam (Latest Update 2025 /
2026) Genetics | Questions & Answers | Grade A |
100% Correct. Portage Learning.
1. Passenger:: Mutation that occurs in cell but does not contribute to
growth
2. Metastasis: Defects in cell that lead to spread of primary tumor to other
areas of body
3. Tumor: Solid mass growth resulting from uncontrolled growth
4. Using the development of colon cancer as an example, explain the
process of tumorigenesis can occur in distinct stages through the
accumulation of mutations.: - Growth of a polyp (adenoma) that is
defective for the APC gene (which codes for differentiation of normal
intestinal cells. Tumor still benign
- Genetic mutation occurs within the adenoma-usually Kras gene which
regulates cellular growth. Cell growth becomes uncontrolled and adenoma
grows

, BIOD 210
- Large adenoma becomes malignant through expansion of tumors that
mutate through other genes responsible for apoptosis, growth signaling, and
cell cycle regulation
- Metastasis occurs and instead of being localized, spreads to areas
outside the colon
5. Most scientists believe that the biggest driver of a cancer phenotype
is:: the inability of teh cancer cell to repair DNA damage 14. True/False:
Few cancer gene mutations are inherited.: True
6. A tumor that is confined to a localized group of tissues is _______.:
benign
7. A tumor that breaks off and invades other tissues is ________.:
malignant
8. BAX family proteins are:: proapoptotic
9. BC12 family of proteins are:: antipoptotic
10. True/False:
The BAX family of proteins are proapoptotic and the BCl2 family of
proteins are antiapoptotic.: True
