K0 WRabbits 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2 Y! q ^" @+ ]8 U
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. g, X, g; x. m& y0 z8 p" j1 Ios.tvboxnow.comFor 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.tvb now,tvbnow,bttvb, K C) A" e) b0 `8 T; B
