Genetic modification. Flashcards
Define Genetic modification.
Genetic modification is changing the DNA of living things, like plants or animals, to make them having specific traits or do certain things.
Describe genetic modification
Genetic modification is changing the genetic material of an organism by:
- Removing,
- Changing,
- Inserting
Individual genes
Why are Human genes inserted into Bacteria?
Inserting Human genes into bacteria allows the bacteria to create human proteins like insulin. We can collect these proteins for medical purposes.
Why are genes added for herbicide resistance?
- Adding genes for herbicide resistance into crop plants helps them survive herbicides.
- As a result, better weed control without hurting the plants.
Why are genes added for insect pest resistance?
- Adding genes to crops for insect resistance helps them fight pests without needing lots of chemicals
Why are genes added for additional vitamins?
- By adding genes to crops, we can boost their nutritional value with things like vitamins or minerals.
- As a result, helps make crops healthier for people to eat.
How is improved yield an advantage of genetically modified crops?
Genetic modification of crops can make them produce more food to feed more people
How is Healthier food an advantage of genetically modified crops?
- Some crops can be made with more nutritional content like vitamins to help us stay healthy
How are genetically modified crops better for the earth?
- Certain genetically modified crops that are more herbicide and pesticide-resistant need less harmful chemicals, which is better for the planet.
How is Loss of Biodiversity a disadvantage?
- Using a lot of genetically modified crops might mean we don’t see as many different types of plants anymore.
How is the mixing of genes a disadvantage?
- Genetically modified crops may crossbreed with regular ones and spread their changes, which could be a problem.
How is the cost a disadvantage?
- Some farmers might end up needing to buy seeds from just a few big companies, which may be costly.
