Genetic engineering has emerged as one of the powerful method in life saving technique. Some scientist have developed a technique to ward off the flaws in parent gene of embryos that can be fatal in future for the child. Report claims itself to be the first experiment of its time that erases the mutant gene from parent , that can appear in offspring and repeat the disease of parent inherently. Some biologist says that the finding might help to correct cancer ,cystic fibrosis and dystrophy causing genetic variation. One of the striking part of this report says is the procedure that the use is one of the controversial technique “Germ line editing”. Which has also given rise to questions against this type of experiment and also asked for banning of this type of experiments in many nations. The main reason behind their claim for banning such useful and life sa
