The Cell Cycle (and cancer) [Updated]
Amoeba Sisters・2 minutes read
Living things are made of cells that work together in body tissues, organs, and organ systems, specializing in different functions, regulated by the cell cycle. Cell reproduction through mitosis and cytokinesis allows growth in multicellular organisms, while treatments like radiation and chemotherapy target cancer cells resulting from uncontrolled division.
Insights
- Specialized cells in multicellular organisms work together in tissues, organs, and organ systems, highlighting the importance of cellular cooperation for overall organism function.
- Cancer, characterized by uncontrolled cell division, can be caused by genetic factors or exposure to toxins, leading to the development of targeted treatments like radiation and chemotherapy to manage the disease.

Recent questions
What is the cell theory?
The cell theory states that all living things are composed of one or more cells.
How do multicellular organisms grow?
Multicellular organisms grow by reproducing cells through mitosis and cytokinesis.
What causes cancer?
Cancer is caused by uncontrolled cell division, often due to genetic factors or exposure to toxins.
How do scientists treat cancer?
Scientists develop treatments like radiation and chemotherapy to target cancer cells that divide frequently.
What are the phases of the cell cycle?
The cell cycle consists of interphase (G1, S, G2) where cells grow and replicate DNA, and M phase where mitosis occurs. Checkpoints ensure cells are growing correctly and replicating DNA accurately before division.
