Note

  • can be used to produce drugs like insulin.
  • has been used to make plants more resistant to pests or tolerant to herbicides.
  • helped env. scientists monitor + solve many problems → related to env. damage.
Applications of Genetic EngineeringBenefit to Society
Low cost production of medicinesGenetic Engineering → of imp. drugs → such as human insulin → drastically reduced cost of these medicines.
With these drugs becoming more affordable → more patients → get access to them + treated
Production of crops that grow in extreme conditions:
→ drought resistant crops
→ salt tolerant crops
→ crops that make more efficient use of nutrients.
Allows farmers → grow crops → even when the env. conditions are not suitable for cultivating most crops.
Development of:
→ crops that produce toxins that kill insect pests.
→ pesticide resistant crops.
Use of costly pesticides → that may damage the env. → is reduced.
e.g. → Bt gene from certain bacterium → can be inserted into plants → produce a toxin that kills certain insect pests.
Development of food designed to meet specific nutritional goalsImproved nutritional quality of foods.
E.g. → 2 genes from daffodil and one gene from bacterium erwinia uredovora → inserted into rice plants to produce golden rice → have high vitamin A content
