And it was through our research to understand the activity of this protein, Cas9, that we realized that we could harness its function as a genetic engineering technology -- a way for scientists to delete or insert specific bits of DNA into cells with incredible precision -- that would offer opportunities to do things that really haven't been possible in the past.
E foi na nosa investigación para entender o funcionamento de Cas9, cando vimos  que podíamos modificar a súa función coma una tecnoloxía de enxeñería xenética un xeito de que os científicos poidan borrar ou inserir fragmentos específicos de ADN en células cunha precisión incrible Isto ofrecería oportunidades  para facer cousas que nunca serían posibles no pasado.
