What you need to know

  • Genetic engineering changes an organism's genome by transferring in a gene for a chosen characteristic.
  • Examples include bacteria modified to make human insulin, sheep modified so a drug is in their milk, and crops modified for yield, quality or resistance.
  • The lesson weighs advantages of those crop changes against the concerns they raise.
  • Gene therapy, treating an inherited disorder in a person, is presented alongside this and is a different use of genes.
