Summary

  • Biotechnology uses organisms or parts of organisms.
  • The use of yeasts and lactic acid bacteria in making breads and cheeses, for example, is a traditional biotechnology.
  • Functional foods have good effects on our health.
  • Plant and animal breeding can be accelerated e.g. cell cultures and genetic engineering.
  • When a gene is transferred from one species to another, we speak of a genetically modified organism (GMO).
  • Microbes are used in industry in many ways.
  • Medicine produces e.g. drugs and new cells through biotechnology.
  • Fertility treatments are also biotechnology.
  • The use of biotechnology is regulated by law and regulations.
  • Previously known concepts: Cell, nucleus, chromosome, gene, DNA, heredity, mold, yeast, bacterium, virus, cell division, sperm, ovum, embryo.
  • New key concepts: biotechnology, breeding, genetic engineering, stem cell, modification, selection, clone, tissue culture, artificial insemination, embryo transfer, gene transfer, genetic engineering, GMO, gene therapy.
