Unfortunately, aspirin also inhibits another enzyme called COX-1, and this enzyme helps to produce the protective layer of mucus that lines the stomach. So taking aspirin makes it more likely that the strong acid in the stomach could damage its walls. People with stomach ulcers are advised not to take aspirin. As we learn more about the complex metabolic pathways that produce enzymes like COX-1 and COX-2, and about the cell-signalling mechanisms involving prostaglandins and other chemicals, it is becoming possible to produce new drugs that have more narrow-ranging effects than aspirin.

This cell was a zygote – a cell that forms when two gametes fuse. The zygote contained a set of chromosomes from your father and a set of chromosomes from your mother. All the cells in your body have developed from this single original cell. Soon after it was formed, the zygote divided to form two cells, which then each divided to form a total of four cells. This division went on and on, eventually forming your body containing many millions of cells. Some cells continue to divide even in an adult.

In some organisms, mitosis is used for reproduction. For example, strawberry plants grow runners which put down roots and produce new, genetically identical plants. This is asexual reproduction, which does not involve gametes or fertilisation. Some animals, for example Hydra, can also reproduce in this way. Single-celled organisms can also reproduce by mitosis. The single-celled fungus, Saccharomyces cerevisiae, yeast, reproduces by budding. 11). Your body contains about 1013 cells. They have all developed from the single cell with which you began your life – the zygote that was formed by the fusion of an egg cell and a sperm cell.
