Gene therapy is a new technique developed by doctors with the idea of treating illnesses and diseases on the molecular level. Gene therapy enables physicians to target a mutated or damaged gene and replace it with a healthy gene.
Director Andrew Niccol imagined a world in which the imperfections built in at birth were erased. His movie "Gattaca" shows a time when people are genetically engineered to be the best combination of their parents' genes. At the beginning of the movie, a genetisist explains, “We want to give your child the best possible start. Believe me, we have enough imperfection built in already. Your child doesn't need any more additional burdens.” (Niccol, 1997). Having children went from a game of chance, to a highly controlled process.
