biotechnology

• give examples of biotechnology

  • mycoprotein
  • insulin producing bacteria
  • gm crops
• describe production of mycoprotein

  1. fungus grown on glucose syrup in aerobic conditions
  2. biomass harvested and purified
• describe production of insulin producing bacteria

  1. isolate insulin gene with enzyme
  2. mix insulin gene with plasmid at same sticky ends
  3. sticky ends join together with enzyme
  4. plasmid inserted into bacteria
  5. insulin harvested and purified
• give advantages of gm crops

  • improve nutritional value
  • develop pest resistance
  • increased growth in environmental conditions
