For the normal cell to become a cancer cell, mutations should take place in protooncogenes to
become oncogenes as well as mutations in tumor supressor genes to be come mutated tumor
supressor genes.
Select one:
True
False
Compare and contrast oncogenes and tumor suppressors. Contrast oncogenes and proto-oncogenes. Describe the types of mutations that convert proto-oncogenes into oncogenes. Summarize some functions of common oncogenes in cell survival and uncontrolled growth. Contrast tumor suppressors to oncogenes. Describe the types of mutations in tumor suppressors that are found in common cancers. Summarize the functions of common tumor suppressors in cell survival and cell growth.
Although cancer is not a contagious disease in humans or other vertebrates, there have been rare cases in which cancers have spread from one organism to another. Describe three cases of these contagious cancers and what conditions might have led to their appearance.

- The decision by some high-risk women to have their breasts removed to prevent the possibility of developing cancer could be a truly life-altering decision. At first glance, this decision could make sense for those women who are at elevated risk due to genetic or family history factors.

- To determine : The number of chromosomes in the HeLa cell. Concept introduction: HeLa cell is the oldest and commonly used cell line that was derived from the cervical cancer cells. HeLa cells differ from the normal cells in many ways. These cells have the ability to contaminate other cell lines. These cells have furthered the understanding of cancer, HIV and the cells in general. It is still used widely to grow viruses and to test anti-tumor medicines.arrow_forwardIn your own words, what is angiogenesis and what is the importance of this process in cancer progression?arrow_forward#1) Hyperplastic growth are not cancerous yet but show a higher than normal proliferation rate.
