Khan Academy: Cancer and the Cell Cycle
Article takes a look at how cancer develops and what's wrong with cancer cells. Also, delves into how abnormal forms of cell cycle regulators can contribute to cancer.
BBC
Bbc: Gcse Bitesize: Cell Division
Chromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same genetic information. Links to a video and a test are provided.

BBC
Bbc: Gcse Bitesize: Dna, Genes and Chromosomes
Chromosomes are made from DNA. Genes are short sections of DNA. Genetically identical cells are produced by a type of cell division called mitosis. In sexual reproduction, a male gamete fuses with a female gamete to produce a new cell....
