10 Questions
What are the 3 checkpoints in the cell cycle?
G1-S, G2-M, Metaphase-anaphase
What is the consequence of DNA not being intact at the G1-S checkpoint?
Cell division will not occur
Describe the process of necrosis.
Cell is assassinated, contents leak out, often irritating surrounding cells
What is the significance of apoptosis in cell death?
Cells break down in an organized manner, contents are packaged and distributed for other cells to use
What is cancer, and what causes it?
When cells ignore cell cycle stop signs, caused by several mutations
Define a benign tumor and explain its characteristics.
A benign tumor is not cancerous and stays in one spot. It may grow larger and crowd nearby cells, impairing normal function.
What is metastasis in the context of cancer?
Metastasis is the spread of cancer cells from the initial location to another part of the body through the blood or lymph system.
Explain the process of cell specialization and differentiation.
Cell specialization is the process by which cells develop into cells that have specific functions within a multicellular organism. Cell differentiation is the process by which cells become specialized.
What are carcinogens and provide examples of them?
Carcinogens are agents that can cause DNA mutation. Examples include radiation (UV ray), virus (HPV), and chemical (tobacco cigarettes).
Describe the treatment methods for cancer mentioned in the text.
The treatment methods for cancer include Radiation Therapy, Chemotherapy, and Surgery. Radiation therapy uses radiation to kill cancer cells, chemotherapy involves chemical drugs, and surgery aims to remove tumors.
This quiz covers cell cycle checkpoints, specialized proteins acting as stop signs, and the factors that prevent cell division. It also discusses cell death and suicide in the body, including the number of cells that die per minute.
