- GM organisms
- Drugs from animals
- Pharming
- Ethical Issues
- Large Quantities - more available
- Harmful side effects for animal
- Hereditary antimicrobial deficiency
- Makes blood clots more likely to form
- Makes blood clots more likely to form
- High yields from goats
- 1. DNA fragments injected into goat embryo
- 2. Embryo implanted into female goat
- When offspring is born - tested if protein is produced
- If yes - Selective Breeding to produce a herd
- When offspring is born - tested if protein is produced
- 3. Protein is extracted from milk
- Makes blood clots more likely to form
- Ethical Issues
- Pharming
- Insect-Resistance Plants
- Soybeans
- Greatly reduced by insect pests
- Important in food production
- Gene originally found in Bacillus thuringiensis (bt)
- Codes for protein toxic to insects
- 2. Inserted back into at
- SB cells infected with transformed bacteria
- 1. Gene isolated from bt - RE & inserted into plasmid
- From Agrobacterium tumefaciers (at)
- 3. Gene inserted into SB cells DNA - GM plant
- Ethic Issues
- Encourage monoculture
- Decrease biodiversity & crops vulnerable to disease
- Decrease no. chemical pesticides
- Encourage monoculture
- 2. Inserted back into at
- Codes for protein toxic to insects
- Soybeans
- Genetic Engineering on pathogens for research
- Treatments for disease
- Tumor cells have receptors on membranes for the poliovirus
- Polio-virus will recognise and attack them
- By GE the PV to inactivate the genes that cause poliomyelitis, scientists can use it to attack and kill the cancer cells without causing a disease
- Polio-virus will recognise and attack them
- Tumor cells have receptors on membranes for the poliovirus
- Ethical Issues
- Treat previously un-treatable diseases
- Mass outbreak of disease
- GM'd pathogen reverts back to original form - outbreak
- Wrong hands = used maliciously
- Treatments for disease
- GE organisms can be 'owned' by big companies
- Different insitutions share knowledge & skills
- GM products produced at a faster rate
- Some = legal protection
- By law, control who uses the product & for a set period of time
- Ethical Issues
- Owner = Generate £ from selling
- Poorer farmers = can't afford GM'd plants
- Different insitutions share knowledge & skills
- Drugs from animals
