Concerns and warnings. Is it really possible to modify human genes?

There is still a glimmer of hope to close the door open by a hereditary world by saying that he has changed the genes of two twins to reach the first genetically modified baby. In an open Internet letter, scientists said that the use of CRISPER-C9 technology to alter human embryo genes was risky and unwarranted, undermining the reputation and development of the biomedical community in China.

In online videos, genealogist He Jian Kui defended what he claimed to have done, claiming that he had genetically altered the twins born this month to protect them from the HIV virus.

"The bioethical ethics review of this so-called scientific research is nominative," said the scientists, in their speech published on the Chinese website "Piper," stating that "direct experiments on the subject are still in progress". men can only be described as "alienating".

There may still be a glimmer of hope to close it before it's too late, "said some 120 scholars in a Chinese-language letter, Yang Qin Gang, a professor at Fudan University. told Reuters that he had signed the letter because the genetic modification was "very dangerous".

CRISP-C9 technology allows scientists to cut and copy DNA in drastic ways, opening up the prospect of genetic reform to prevent disease. There are, however, ethical and security concerns with this technology.
