Essential Idea:
Cell division is essential but must be controlled
Cell division is essential but must be controlled
Understandings:
- Mitosis is division of the nucleus into two genetically identical daughter nuclei
- Chromosomes condense by supercoiling during mitosis
- Interphase is a very active phase of the cell cycle with many processes occurring in the nucleus and cytoplasm
- Cytokinesis occurs after mitosis and is different in plant and animal cells
- Cyclins are involved in the control of the cell cycle
- Mutagens, oncogenes and metastasis are involved in the development of primary and secondary tumours
Applications:
- The correlation between smoking and incidence of cancers
Skills:
- Identification of phases of mitosis in cells viewed with a microscope or in a micrograph
- Determination of a mitotic index from a micrograph

Theory of knowledge:
Theory of knowledge:
A number of scientific discoveries are claimed to be incidental or serendipitous. To what extent might some of these scientific discoveries be the result of intuition rather than luck?
International-mindedness:
International-mindedness:
Biologists in laboratories throughout the world are researching into the causes and treatment of cancer.
The TED video on the right is a talk by David Agus. He is example of cancer researcher working on new, cross-disciplinary approach, using atypical drugs, computer modeling and protein analysis to diagnose and treat the whole body
