Rabbits join a growing list of fluorescent fur-bearers. Genetic engineers have created glowing dogs, cats, pigs and mice by inserting a gene from a jellyfish into the mammals’ DNA. The jellyfish gene codes for a protein that emits light when exposed to ultraviolet light.公仔箱論壇/ p G" t* }8 }- l
The jellyfish gene adds an obvious physical change to an engineered animal. This allows scientists to know that genetic material successfully transferred into a new organism.TVBNOW 含有熱門話題,最新最快電視,軟體,遊戲,電影,動漫及日常生活及興趣交流等資訊。0 F6 {; V( Z6 U q y: B7 \2 [
For example, when Mayo Clinic researchers genetically engineered cats to carry a protein that defends the animals from infection by the feline immunodeficiency virus (FIV, the cat version of HIV), the scientists added the fluorescent gene along with the FIV-resistance gene. That way they knew that any cat that fluoresced also carried protein protection against FIV, a trait that would otherwise be invisible. - B% u.
