Which of the following accurately compares tumor suppressor genes and proto-oncogenes?
A. Both tumor suppressor and proto-oncogenes prevent the spread of cancer by targeting and destroying existing cancer cells.
B. A person who has both tumor suppressor and proto-oncogenes will always develop cancer.
C. Proto-oncogenes code for growth factors, while tumor suppressor genes inhibit cell division of damaged cells.
D. When a proto-oncogene mutates, it becomes a tumor suppressor gene.
With regard to cancer cells, which of the following are true?
A.
Cancer cells are clonal, meaning that they are derived from many different cells that all underwent the same clonal mutation.
Cells usually accumulate many mutations over time, and this results in cancerous growth.
B.
Almost all cancers are caused by oncogenic viruses.
no Benign tumors are dangerous because they can easily invade surrounding tissue and spread to other locations in the body.
DE.
Cancer cells are unable to control their division.
Which of the following steps are correct about multistep tumorigenesis (select all that apply)?
A.
Mutations in progenitor cells are more likely to develop a neoplastic state compared to mutations in stem cells
B.
Driver mutations give a cell clone a proliferative advanage
C.
The rate of mutation /genetic change is constant during tumor progression
D.
Nutrition/diet may effect rate of tumorigenesis
E.
All cells within a tumor are biologically equivalent and equally capable of high levels proliferation

- The Human papillomavirus (HPV) has been linked to an increased risk of cervical cancer. The HPV E6 and E7 proteins govern the cell via altering cellular proteins. The E6 protein interacts with the tumor suppressor protein p53 and directs its ubiquitin-mediated destruction.

Thank you!arrow_forwardWhich of the following statements concerning p53 is NOT correct? O a. p53-dependent transcription of target genes leads to cell cycle arrest or cell death (apoptosis). O b. O C. Loss of p53 function results in loss of checkpoint controls. Loss of p53 function creates an environment that is permissive for genome instability--that is, more damaged cells with chromosome aberrations and mutations survive and propagate. d. p53 is a tumor suppressor protein which is largely responsible for protecting cells from cancer- causing DNA-damaging agents.arrow_forwardSometimes, malignant cells do not stay properly anchored in tissues because of the loss of function of: a. cell walls b. oncogenes c. plasma membrane adhesion proteins d. nuclear membranes e. tumor suppressor genesarrow_forward
