Detailed explanation-1: -In 1997, a 7-month-old sheep named Dolly became a celebrity. Dr. Ian Wilmut, a Scottish scientist, announced to the world that he had created her using a procedure called cloning.
Detailed explanation-2: -It was 20 years ago today that Dolly the sheep was born, the ultimate product of a series of cutting-edge cloning experiments that would soon rock the research world. Animals had been created from embryonic cells before, but Dolly was the first mammal successfully cloned from an adult cell.
Detailed explanation-3: -After Dolly gave birth to her last lambs in September 2000, it was discovered that she had become infected by a virus called Jaagsiekte sheep retrovirus (JSRV), which causes lung cancer in sheep. Other sheep at The Roslin Institute had also been infected with JSRV in the same outbreak.
