Scientists can remove a gene from one organism and insert it into the DNA of another organism - genetic engineering

  • For example, scientists have inserted the gene from human insulin into bacterial plasmid DNA. 
  • The genetically modified (GM) bacteria can then make human insulin, which is used by people with diabetes. 
  • Organisms like these bacteria are known as Genetically modified organisms (GMOs).

The production of human insulin by genetically modified (GM) bacteria has many advantages. 

  • Insulin used to be extracted from dead cattle and pigs but insulin from GM bacteria can now b used by vegans.
  • It also means that the supply of insulin is not affected by animal diseases or the number of animals slaughtered
