South Korean scientists have cloned cats by manipulating a fluorescent protein gene, a procedure which could help develop treatments for human genetic diseases, officials said Wednesday. In a side-effect, the cloned cats glow in the dark when exposed to ultraviolet beams. A team of scientists led by Kong Il-keun, a cloning expert at Gyeongsang National University, produced three cats possessing altered fluorescence protein (RFP) genes, the Ministry of Science and Technology said.
