Cancer Biology Questions and Answers Latest Version Already Passed
What is the primary characteristic of cancer cells that differentiates them from normal cells?✔✔ Cancer cells have uncontrolled cell division and fail to undergo apoptosis.
In cancer biology, what role does the mutation of proto-oncogenes play in the development of cancer?✔✔ Mutations in proto-oncogenes convert them into oncogenes, which promote excessive cell division.
How do tumor suppressor genes contribute to cancer prevention?✔✔ Tumor suppressor genes inhibit cell division and promote apoptosis, preventing the development of tumors.
What is the process by which cancer cells spread from their original location to other parts of the body called?✔✔ Metastasis.

What is the significance of the p53 gene in cancer biology?✔✔ The p53 gene is a tumor suppressor gene that regulates the cell cycle and initiates apoptosis in damaged cells.
How do angiogenesis inhibitors play a role in cancer treatment?✔✔ Angiogenesis inhibitors prevent the formation of new blood vessels, depriving tumors of the oxygen and nutrients they need to grow.
What is the role of telomerase in cancer cells?✔✔ Telomerase is often reactivated in cancer cells, allowing them to maintain telomere length and avoid cell death, contributing to their immortality.
What is the function of immune checkpoint inhibitors in cancer therapy?✔✔ Immune checkpoint inhibitors block proteins that prevent immune cells from attacking cancer cells, allowing the immune system to fight the cancer more effectively.
How does the Warburg effect contribute to cancer cell metabolism?✔✔ The Warburg effect describes the tendency of cancer cells to rely on glycolysis for energy production even in the presence of oxygen, which supports rapid cell growth.
