- Genetic Engineering
- Genetic engineering is the manipulation of an organisms genetic material to change or add a certain characteristic.
- A useful gene is cut from an organisms DNA using enzymes.
- Enzymes are used to cut another organisms DNA and then to insert the useful gene.
- This technique creates genetically modified organisms.
- Enzymes are used to cut another organisms DNA and then to insert the useful gene.
- Genetic engineering can benefit humans:
- Golden rice contains beta carotene, a source of Vitamin A derived from daffodil.
- With golden rice as part of a diet, fewer people will suffer from Vitamin A deficiency and it will help prevent blindness and treat malnutrition in the third world.
- The human insulin gene can be inserted into bacteria to produce human insulin which is limited in supply.
- Scientists have managed to add genes to plants which can make then herbicide resistant.
- Fields of crops can be sprayed with a herbicide and kill all the plants or weeds except the modified plants. This increases crop yield of the crop which could target famine in poorer countries.
- Golden rice contains beta carotene, a source of Vitamin A derived from daffodil.
- Genetic engineering is a controversial topic because:
- The development of herbicide resistant weeds.
- There is no proof that genetically modified crops are safe.
