- Genetic engineering
- Uses...
- Finding out where genes are expressed in the body
- crops produce a greater yield
- disease resistant crops
- Manufacturing insulin
- Restrictive enzyme used to split a DNA and split the insulin from the rest of chromosome
- Insulin gene placed into plasmid and sealed with the enzyme ligase
- plasmid is then put into some bacteria
- The bacteria reproduces exact copies
- The human insulin is removed and purified
- The bacteria reproduces exact copies
- plasmid is then put into some bacteria
- Insulin gene placed into plasmid and sealed with the enzyme ligase
- The same is done to a plasmid of bacteria
- Insulin gene placed into plasmid and sealed with the enzyme ligase
- plasmid is then put into some bacteria
- The bacteria reproduces exact copies
- The human insulin is removed and purified
- The bacteria reproduces exact copies
- plasmid is then put into some bacteria
- Insulin gene placed into plasmid and sealed with the enzyme ligase
- vantages
- increases genetic diversity
- Infectious disease treated
- Moral issues
- animals can be 'tailor made' to show desirable characteristics
- Prevents disease
- We don't know the consequences
- GM crops pros and cons
- No insects killed
- producers earn money when selling
- expensive seeds
- passed through pollination to wildlife
- Safety of food is not yet determined
- no evidence for the effectiveness
- Uses...
