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. * L/ l/ y+ v# ]- x* ~. @5 twww.tvboxnow.comThe 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. 9 D" ], L V9 Y! Ctvb now,tvbnow,bttvbFor 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.www.tvboxnow.com! p) `6 a7 M1 n( q g0 k
