genetic engineering

• genetic engineering 


  to transfer a gene responsible for desirable characteristics from one organisms genome to another organism, so that it also has the desired characteristics
• how have plant cops been genetically engineered?

  engineered to be resistant to diseases or to produce bigger better fruits.
• how can bacterial cells be genetically engineered?

  to produce useful substances such as human insulin to treat diabetes
• gene therapy 


  inserting working genes into people with diseases
• what is the concern with genetic engineering?

  worries about long term effects, that changing an organisms gene might accidentally create unplanned problems, which could get passed on to future generations
• pros of GM crops

  • can increase the yield, making more food
  • croos could be engineered to contain a nutrient that’s missing
  • GM are being grown in places without any problems
• cons of GM crops

  • reduces farmland biodiversity
  • dont fully understand the affects they have in human health
  • transplated genes may get out into the natural environment
