【英语介绍克隆羊DOLLY】Summary:
Dolly the Sheep was the first mammal to be successfully cloned from an adult somatic cell using the process of nuclear transfer. She was born on July 5, 1996, at the Roslin Institute in Scotland, and her creation marked a significant milestone in the field of biotechnology and genetic research. Dolly's birth proved that it was possible to create a genetically identical copy of an adult animal, which had previously been considered impossible. Her life sparked global interest and debate about the ethical implications of cloning technology. Dolly lived for nearly six years before passing away due to a progressive lung disease, which some scientists believed might be related to the aging process of her donor cells.
