Have you ever imagined that you could be cloned(克隆) like Dolly, the sheep, in the not too distant future?
The news that a human embryo(胚胎) has been 16 cloned for the first time has caused mixed reactions(反应).
The 17 was carried out by scientists from the Advanced Cell Technology Inc(ACT), in Massachusetts, US. The group 18 the news on November 25.
This is 19 human being. A clone is alive, it walks, it breathes, said Jamie Grifo, a(n) 20 on the study of cloning at New York University School of Medicine.
“This is a set of cells in a lab that will be used to 21 someone’s life.”
Such research could lead to treatment for 22 such as heart disease, AIDS and even cancer, 23 scientists.
Despite high hopes from other scientists, the news raised concerns immediately from religious and political leaders. Several 24 in the US do not allow human cloning. President George W. Bush also made it clear that he is 25 any type of human cloning. However, the scientists at ACT said they have no interest at present in 26 an early embryo into 27 .
Animal have been cloned repeatedly since Dolly, the sheep 28 in 1997. And there were no real technical 29 to stand in the way of scientists making a cloned human embryo.
This time the research group used traditional cloning technology with a human 30 . 31 it was given DNA from an adult cell, the egg began to 32 . 33 it was stopped from becoming a baby-at a stage in which it was 34 a ball of cells. The 35 technology has been used to clone sheep , cattle and monkeys.
