24、cide to have another baby just like you. It might be flattering(讨人喜欢的), but how would you feel about having a little brother or sister who is also your twin A laboratory experiment conducted last fall suggests it may someday be possible. For the first time ever, scientists made exact copies, or clon

25、es(克隆), of a human embryo. Although the embryos grew for only six days, cloned embryos could theoretically be implanted in a womans womb(子宫)and develop into normal babies. Or they could be frozen and implanted years later. The scientists developed their cloning technique to make it easier for childl

26、ess couples to have babies by in vitro(在体外的)fertilization. In this procedure, sperm(精子) from the man fertilizes an egg from the woman in a laboratory dish. In most case, doctors must try implanting several embryos before one stays in the womb. Cloned embryos would give them many more embryos to impl

27、ant. But the technique could also be used for other purposes. Parents might freeze embryos cloned from their children so that they could be replaced if any of them died. The clones would also be ideal donors if the children needed organ transplants. Another possibility: Childless couples could go to

28、 a bank of frozen embryos and choose a child just like one whos already living. Some people are concerned that these couples might pick only beautiful, successful children. The ethical dilemmas(困境)of cloning have not yet been discussed fully because the public assumed it was a long way off. Many peo

29、ple are calling for(要求，提倡)controls on cloning immediately before the practice is abused.

Researchers in Texas hope that people who eat the potatoes will be protected against common gut(肠，肠子) infections. They believe this techni

35、que could prove to be a cost-effective way of growing vaccines in developing countries where such diseases are still killers. Other researchers previously succeeded in using similar techniques to produce potential vaccines Now Hugh Mason and his colleagues at Texas A & M University(得克萨斯农业及机械大学) thei

36、r plant vaccines on mice and plan to recruit 15 volunteers for a human trial. The team first tested the technique in tobacco plants. They took a strain of Escherichia coli(大肠杆菌) bacteria that causes food poisoning, and identified the part of the poison which binds to its victims gut cells. They then

37、 used a modified plant bacterium called Agrobacterium tumefasciens to transfer the segment of DNA which manufactures the binding protein into the tobacco plant. Under normal circumstances, these bacteria transfer packets of DNA into plant cells to force the plant to manufacture the nutrients they ne

38、ed. But in the modified bacteria, the DNA package includes the gene to pro- duce the binding protein. Once the foreign DNA segment was incorporated(结合，合并) into the tobaccos own DNA, the bacteria were killed off with antibiotics. Masons team then grew these modified tobacco plants and found that they

39、 produced the E. coli binding protein. Proof of success came when the tobacco leaves were mashed up(捣碎) and squirted into the stomachs of mice. Mason says that within days the mice started producing specific antibodies to the E. coli poison, but suffered no ill effects from digesting the binding pro

40、tein. Mason then produced genetically engineered potatoes and fed these to mice, with similar results. Masons team have used plants to produce vaccines against a number of other infectious agents. For example, they have made a vaccine using a protein from the shell of the Norwalk virus, which causes

41、 diarrhoea(腹泻) in children. A third vaccine has also been produced in tobacco using a surface protein from the hepatitis B virus. But Mason says that so far they have only been able to produce small amounts of it in potatoes. Although a vaccine already exists against hepatitis B, a cheaper plant ver

42、sion could make mass immunisation(群众性免疫) possible. One problem with growing potatoes to produce vaccines is that cooking tends to destroy the protein component of the vaccine, so they must be eaten raw. Mason thinks that bananas may be a better option. One banana could potentially produce a whole ho
