¡¡ ¡¡ Have you imagined that you could be cloned like Dolly the sheep in the not-too-distant future?

¡¡¡¡¡¡¡¡ The news that a human embryo(ÅßÌ¥) has been¡¡¡¡ ¡¡¡¡¡¡¡¡ 16¡¡ cloned for the first time has caused mixed reactions.

¡¡¡¡¡¡¡¡ The 17¡¡ was carried out by scientists from the Advanced Cell Technology(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 treatments 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(×ڽ̵Ä) 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 ¡¡¡¡¡¡¡¡¡¡¡¡ .

¡¡¡¡¡¡¡¡ Animals 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 tradition 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 stage in which it was ¡¡ 34¡¡¡¡¡¡¡¡¡¡¡¡¡¡ a ball of cells.

The 35¡¡¡¡¡¡¡¡¡¡¡¡¡¡ technology has been used to clone sheep, cattle and monkeys.
