By day he is just a normal cat but when the lights go out, he glows (发光) in the dark.
Scientists have genetically modified (更改) a cat as part of an experiment that could lead to treatments for diseases.
Named Mr. Green Genes, he looks like a six-month-old cat but, under ultraviolet (紫外线的) light, his eyes, gums (牙龈) and tongue glow green. That is the result of a genetic experiment at the Audubon Center for Research of Endangered Species in New Orleans, US.
Mr. Green Genes is the first fluorescent (荧光的) cat in the US and probably the world, said Betsy Dresser, the center's director.
The researchers made him so they could learn whether a gene could be introduced harmlessly into a cat's genetic sequence (次序).
If so, it would be the first step in a process that could lead to the development of ways to treat diseases via gene therapy (治疗).
The gene, which was added to Mr. Green Genes' DNA, has no effect on his health, Ms Dresser said.
Cats are ideal for this project because their genetic makeup is similar to that of humans, said Dr Martha Gomez, a scientist at the center.
To show that the gene went where it was supposed to go, the researchers settled on one that would glow.
The gene "is just a marker", said Leslie Lyons, an assistant professor at the University of California, Davis. Lyons is familiar with the center's work.
"The glowing part is the fun part," she said.
Glowing creatures made international news earlier this month when the Nobel Prize in Chemistry was awarded to three scientists who had discovered the gene through their work with jellyfish (水母).

查看习题详情和答案>>WASHINGTON, Sept. 23—The House of Representatives, which prides itself on being “the People’s House” has been turning into a rich man’s club.
The representatives newly elected in 1984 were almost four times as wealthy as the first term lawmakers elected only six years before, according to a new study on the members’ financial reports.
Behind this remarkable swing, the study says, are two main factors: a court decision that outlawed limits on what candidates could give to their own campaigns, and the enormous growth in the cost of pursuing a seat in congress. As a result, it is increasingly difficult for candidates of modest means, particularly women to amount successful challenge to entrenched office holders.
One solution, the authors contend, is a system of public financing for campaigns, but congress seems in no mood to change the political rules any time soon.
“The lower chamber is going upper class,” said Mark Green, the president of The Democracy Project, a public policy institute based in New York. “But this evolution from a House of Representatives to a House of Lords denies the diversity of our democracy. It establishes a de facto property qualification for office that increasingly says: low and middle income need not apply.
The Democracy Project produced the study in cooperation with the United States Public Interest Research Group, a similar institute situated in Washington. But their research was not entirely theoretical. In 1980 Mr Green was the unsuccessful Democratic candidate for Congress in New York’s 15th District, in Manhattan. The winner was Bill Green, one of the wealthiest members of Congres

B. The House of Representatives was made up of people with low and middle income.

B. The new study based on the members’ financial reports.
C. A court decision that outlawed limits on what candidates could give to their own campaigns.
D. The representatives elected now are much wealthier than those elected a few years ago.

A. Any honest man can become a representative of the House.
B. Women are more difficult than men to be an entrenched office holder.
C. Limits on what a candidate could give to his campaign are outlawed.
