  • Biotechnology involves using living organisms to create new products.
  • Golden Rice is an example of a biotechnologically developed food with higher yield and enhanced nutritional value.
  • Modern biotechnology techniques aim to produce foods with higher yields and improved nutrition.
  • For exams, students should understand biotechnical and agricultural solutions like genetic modification to meet the needs of the growing human population.
  • Genetically modified (GM) crops can provide more food or food with improved nutritional value, such as Golden Rice.
  • Golden Rice is genetically modified to contain extra vitamin A, providing essential nutrients to consumers.
  • In agriculture, microorganisms are cultured for food production, such as the fungus fusarium used to produce myprotein, a vegetarian protein source available in supermarkets.
  • Fusarium is grown on glucose syrup in aerobic conditions, where the biomass is harvested and purified for food production.
  • Biotechnology also extends beyond agriculture, such as using genetically modified bacteria to produce human insulin for treating diabetes. This involves inserting a gene for insulin into a plasmid, which is then introduced into bacteria for insulin production.
