Scientists grow embryos from three parents

The video explains how human embryos can be created using genetic material from three parents. It describes the two types of DNA: nuclear DNA, which is inherited from both parents, and mitochondrial DNA, which is inherited from the maternal side. A technique is introduced that allows women with mitochondrial disorders to prevent passing these disorders to their children by using a donor egg. The donor egg's nucleus is replaced with the mother's nucleus, and after fertilization, the embryo contains genetic material from both parents and a small amount from the donor mitochondria, ensuring the child is free from the mother's mitochondrial disorder.
