Seven embryos were changed during in vitro fertilization treatment and it was revealed that twin babies were born on the first attempt.
The experts point out that if its statement is confirmed, it will open a new era in terms of genetic science and ethics.
"Human experience"
Genetic design is banned in many countries because there are fears that changes in DNA may be transferred to future generations and that other genes may be damaged.
Some experts say that these tests, which they call "human experiments", are very risky.
He added that these experiments on embryos were intended to help immunize the AIDS virus against HIV. It is said that a small number of people have this ability from birth.
It was recorded that all men participating in the study were carriers of the HIV virus. In the embryos of the experiment, the CCR5 gene, which constitutes a protein allowing the HIV virus to enter the cell, is deactivated.
He Jiankui's claim has not yet been verified by independent sources. The Chinese scientist has not yet published the results of the experiment in a scientific journal.
However, it is stated that an American doctor participated in the experiments. In the United States, such experiments are prohibited.
In China, where human cloning is banned, genetic design research is not limited. (BBC ENGLISH)
