genetic modification

• What is genetic engineering?


  It is the process of modifying the genome of an organism by adding genes from another species.
• Why is genetic engineering used in agriculture?


  To give crops desired traits such as disease resistance and higher yields.
• How does genetic engineering benefit medicine?


  It allows for the production of human insulin by genetically modified bacteria.
• What are the main applications of genetic engineering?


  • Agriculture:
  • Disease and pest resistance
  • Higher yields and better quality crops
  • Medicine:
  • Production of human insulin
• What is the first step in the genetic engineering process?


  Isolating the gene from the DNA using enzymes.
• What is a vector in genetic engineering?


  A vector is a vehicle, like a bacterial plasmid or virus, used to insert genes into target cells.
• Why are genes introduced at an early stage in the genetic engineering process?


  So the organism develops with the desired trait.
• What are some traits of GM crops?


  • Insect resistance
  • Herbicide tolerance
  • Increased yields
  • Reduced loss from pests
• What are some risks and concerns associated with GM crops?


  Environmental impact, human health concerns, and ethical objections.
• What is a potential environmental impact of GM crops?


  Effects on wildflowers and insects.
• What are ethical objections to genetic engineering?


  Some people oppose genetic modification due to ethical reasons.
• How is genetic engineering being explored for future medical treatments?


  It is being researched for treating inherited disorders in humans.
• What key skills should students develop regarding genetic engineering?


  • Understand benefits and risks of genetic engineering
  • Interpret and discuss issues related to GM crops and cloning
