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.: ~' e Q4 r/ _& X. _5 }
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. % h' X; D: u9 x% \6 y6 C9 ktvb 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.tvb now,tvbnow,bttvb1 h5 q5 o0 S6 q0 }" |
