- genetic engineering
- genetic engineering is changing the genome (the DNA) of an organism
- genes can be transferred from any kind of organism to any other organism
- how genetic engineering works
- the gene for a characteristic is 'cut out' of a chromosome using enzymes
- the gene is inserted into a chromosome inside the nucleus of a cell in a different organism
- the cell of this organism now produces the characteristics from the gene
- GM crops
- GM crops have been genetically modified to give them new characteristics
- resistance to attacks by insects and resistance to herbicides
- GM crops have been genetically modified to give them new characteristics
- human insulin in bacteria
- Diabetes is a disorder in which the body's blood glucose levels remain too high because glucose is not effectively removed from the blood
- It can be treated by injecting insulin.
- The injected insulin acts just as natural insulin and causes glucose to be taken up by the liver and other tissues
- this results in cells receiving the glucose they need, and blood glucose levels stay normal.
- The injected insulin acts just as natural insulin and causes glucose to be taken up by the liver and other tissues
- It can be treated by injecting insulin.
- Bacterial cells have been genetically modified to produce substances such as human insulin.

- ethics
- There are ethical issues involved in genetic modification
- there are concerns about the possible health risks of genetically modified food.
- For example, a genetically modified food might contain a substance that causes an allergic reaction in some people, or higher levels of a toxin naturally found in the food.
- there are concerns about the possible health risks of genetically modified food.
- Others think it is ethically wrong to create new life forms, or to move genes between different species.
