There will soon be babies in the UK with DNA(基因) from three people. A new way will stop babies coming to the world with a bad disease. The disease affects about one in 6,500 children around the world. The first baby could come to the world next year. There may be about 150 babies coming to the world each year using this new way.
The way is easy. Doctors take out unhealthy DNA from the mother's egg and put in healthy DNA from another woman. Doctors say this is "light at the end of a dark night" for many families. Britain's leader said many parents could now have a healthy baby. Other people say this is bad. It could lead to "designer babies".
