What this unit covers

• Biotechnology and genetic modification: Identify that bacteria are beneficial in biotechnology and genetic modification because they reproduce quickly and can produce complex molecules.
• Biotechnology and genetic modification: Explain the reasons bacteria are advantageous in biotechnology and genetic modification, focusing on: (a) minimal ethical issues regarding their manipulation and growth, and (b) the existence of plasmids.
• Biotechnology: Explain how anaerobic respiration in yeast contributes to the production of ethanol used in biofuels.
• Biotechnology: Explain the function of anaerobic respiration in yeast during the process of making bread.
• Genetic modification: Explain genetic modification as the alteration of an organism's genetic material by adding, changing, or removing specific genes.
• Genetic modification: Provide examples of genetic modification, such as: (a) adding human genes to bacteria to create human proteins (b) adding genes to crops for herbicide resistance (c) adding genes to crops for insect pest resistance (d) adding genes to crops to enhance nutritional value.
