The woman’s egg is then removed from the ovary with the help of a special needle. The egg is fertilized and is allowed to grow into an embryo for 2 days. Scientists then screen for genes which have the risk of illness in life like Alzheimer's, Cystic fibrosis and Down’s syndrome. The DNA copies are run through by using a sequencing machine. If the genetic disorder appears, those defected genes can be replaced with the healthy genes in a process called germ line therapy. Besides, scientists are able to...
