A glowing bunny sounds like a creature from Jefferson Airplane’s psychedelic-laced song, “White Rabbit,” but real fluorescent rabbits were recently born at the University of Istanbul, Turkey.tvb now,tvbnow,bttvb6 n0 f0 z5 H: M: Y
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& w; ]& Z2 b$ I/ g- y
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.1 p1 j! F6 i) V$ M
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.www2.tvboxnow.com& f- `, D7 C! Y% k. c2 q) [" l
