Dolly – The cloned Sheep
She is the result of research conducted by Dr. Ian Wilmut at the Roslin Institute in Edinburgh, Scotland.
Scientific world was in a shock yesterday when researchers defied Mother Nature by cloning a mammal that could potentially open the door towards copying human beings. Dolly the sheep, as the first successful mammal to be cloned from an adult cell, is by far the world's most famous clone. However, cloning phenomenon has existed in nature since the dawn of life. From asexual bacteria to budding in hydra, clones are all around us and are fundamentally no different to other organisms. A clone has the same DNA sequence as its parent and so they are genetically similar.
In 1996, cloning was revolutionized when Ian Wilmut and his colleagues at the Roslin Institute in Edinburgh, Scotland, successfully cloned a sheep named Dolly. Dolly was the first cloned mammal. Multitude clones had been produced before in the lab before Dolly, including mice, frogs, and cows, which had all been cloned from the DNA from embryos. Dolly was remarkable in being the first mammal to be cloned from an adult cell. This was a major scientific achievement as it demonstrated that the DNA from adult cells, despite having specialized as one particular type of cell, can be used to create an entire organism. Dolly (5th July 1996 – 14th February 2003) was a female domestic sheep, and the first mammal to be cloned from an adult somatic cell, using the process of nuclear transfer. She is the result of research conducted by Dr. Ian Wilmut at the Roslin Institute in Edinburgh, Scotland. Dolly the sheep, was produced as part of research into producing medicines in the milk. The feat opens the door to cloning prize cattle and animals used to make health products, like human blood clotting factors for hemophiliacs. Let's learn more about its reproduction and development.
