Animation: What is gene editing and how does it work?

Watch this short animation to learn about developments in gene editing and their implications for human health

Gene editing allows scientists to change gene sequences by adding, replacing or removing sections of DNA.

This animation explains how this technology works, as well as its possible ethical and societal implications.

This video was produced by the Wellcome Trust. You can learn more about Wellcome’s work on gene editing here.

Questions for discussion

  • What do you think gene editing should and shouldn’t be used for? What would be going too far with the technology?
  • Lots of potential applications of genome editing are mentioned in the video. Can you think of any others?
  • Who should get to decide whether a gene gets edited?
