Summary

  • The gene-editing technique called CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) enables scientists to precisely modify DNA.
  • Exploiting a bacteria’s naturally occurring defense system, it consists of a protein that can edit specific stretches of genetic material and a “genetic GPS” that guides the protein to the right spot.
  • After its discovery five years ago, the tool has been used to genetically modify virtually every kind of organism (including humans) and has led to the development of a multitude of new technologies with the potential to treat human diseases.
  • It has also unintentionally produced the first gene-edited humans and brought about a new breed of ethical dilemmas.
