Professor & # 39; Chinese university Jiankui He announced that GM created the first child. With Crispr technology, both girls turned to DNA can not be infected with the Hiv virus virus, he said. His claims have not been confirmed by & # 39; independently, but many scientists are critical, according to foreign news agencies.
The girls asked Lulu and Nana is born with & # 39; estrakorporali normal fertilization. However, they used white has changed before inserted into the uterus. "Immediately after the sperm & # 39; her husband was sent to the egg, embryo sent him also protein called Cas9 and instructions for operation of the gene intended to prevent the infection of girls from the liver in the future", explained in & # 39; video released Sunday Youtubu.
The operation of the system consists Crispr & # 39; a small portion of protein and RNA Cas9, which cut DNA at & # 39; direct site by a short chain & # 39; RNA. Crispr therefore acts as a smart scissors, which are run at a specific location in the genome, and the field, if necessary, even in & # 39; many places at the same time. Therefore, using the & # 39; this method, scientists can repair and / are replacing genes & # 39; any organism.
The identity of parents and children has not been disclosed, but Shenzhen scientist said his father was a beehive, and he wanted to prevent his son to suffer discrimination.
Scientific claims have not been confirmed by & # 39; independently by scientists. B & # 39; more specifically, they will submit in & # 39; & # 39 international conference, experts from the field, which will begin on Tuesday at & # 39; Hong Kong.
The MIT magazine Technology Review, published an article about the findings of & # 39; Hay, emphasized that this technology "is ethically controversial because fetal changes can inherit future generations can also affect collection full gene ".
Professor of philosophy at the University & # 39 Lowell, Massachusetts, Michigan, Nicholas Evans, meanwhile, said that "by announcing test & # 39; YouTube is a very problematic form of & # 39; scientific practice." "Put away from procedures & # 39; check which there are many scientific advances, such as checking among colleagues", he added.
"We have been talking about genetic engineering of embryos for some time now", he added. "It's more revolutionary that these two children were allegedly altered to be resistant to the disease", he stressed.
