　　日本培育出转基因猴子

　　VOICE ONE:

　　This is SCIENCE IN THE NEWS, a program in VOA Special English. I'm Bob Doughty.

　　VOICE TWO:

　　And I'm Shirley Griffith. This week, we will tell about a study involving monkeys and a gene from jellyfish. We will tell about an agreement to ban nine dangerous chemicals. We will also report on problems linked to cigarette smoking and alcoholic drinks.

　　(MUSIC)

　　VOICE ONE:

　　Scientists in Japan say they have produced monkeys with a gene that gives the skin of the animals an unusual look. The skin is said to look bright green under ultraviolet lighting.

　　The scientists say the monkeys represent an important step in how researchers study human disease. These marmosets are the first fully transgenic primates. Primates are the biological group of animals that includes monkeys and apes. An animal that has received foreign genetic material is considered transgenic.

　　VOICE TWO:

　　For almost thirty years, researchers have used transgenic mice to carry out biomedical research. To produce these animals, researchers inject fertilized mice eggs with foreign genes, and then place them in the uterus of a female mouse. The specially chosen genes are then expressed in some of the mouse's babies.
