Lesson details

Key learning points

  1. Genetic engineering involves modifying the genome of an organism by adding DNA from another organism.
  2. The aim of genetic engineering is to introduce a desirable characteristic.
  3. Examples of genetically engineering crop plants and bacteria to benefit humans.
  4. Benefits must be weighed against risks and ethical questions.

Keywords

  • Gene - a section of DNA carrying the genetic code that provides the instructions for a feature or process

  • Genetic engineering - the process of introducing a gene from one organism into the genome of another organism

  • Risk - the chance that an outcome (usually a negative one) will occur

  • Ethical question - a question about whether something is right or wrong

Common misconception

Over-estimating the risks of genetic engineering and genetically modified (GM) organisms.

The lesson explores the need to weigh up possible benefits, risks and ethical questions when making decisions about genetic engineering.

When exploring the examples, ask pupils to practice suggesting for themselves the possible benefits and risks (and to whom), and identifying ethical questions. Use prompt questions or a simple writing frame to guide their thinking.
