GMOs are mainly used to produce crops that are herbicide-resistant or produce pesticides. The major criticisms of GMOs are related to the overuse of specific herbicides. What is CRISPR, the gene editing technology that won the Chemistry Nobel prize? These technologies are being applied to provide a range of benefits, from improved nutrition in food, to reduced food waste and increased crop tolerance against climate stresses. Unlike with GMOs, this introduces only minor modifications, which are indistinguishable from natural mutations.Īlthough GMOs and gene-edited foods have been in circulation for almost three decades, research in this space continues to deliver breakthroughs. Using techniques such as CRISPR/Cas, scientists make precise “cuts” in the DNA to create new genetic variation. Gene editing involves making precise changes to an organism’s genome without the integration of foreign DNA elements.
