On July 5th 1996 the very first cloned mammal was born
Blackface Sheep 6ll3 or Dolly was created by the Roslin Institute in Scotland
Dolly was brought into existence using the process of somatic cell nuclear transfer
Somatic cell nuclear transfer is when the nucleus which contains most of the genetic information in a cell is taken from a cell in the mammary gland of an adult animal. Then the nucleus of an unfertilized egg is removed and then replaced with the nucleus from the mammary gland. The egg was stimulated to develop into an embryo which was then implanted into the mother.
This was a major breakthrough because previously cloning was only considered to be possible with the use of embryonic cells, but they had just proved that you could successfully use cells from the adult body to clone …show more content…
Now scientists have used this process of somatic cell nuclear transfer to create clones of nearly 20 different species of animals
Scientists do not see a reason to clone humans
Instead they plan to use this knowledge to further their studies in stem cell therapy, for example they would use a patient's cells to create an embryo and then they could see how that patient's disease will affect them over time by comparing it to the embryo
Dolly lived her entire life at the Roslin Institute until she was put down
She had been battling with arthritis and eventually was diagnosed with lung disease
Since Dolly was put down at age six and the average life span of her breed is 10-11 years this validated many people’s fears that clones would not live as long as humans
Dolly also had four other “sisters” who suffered very similar fates that she did
However the Roslin institute is nowhere near done studying this process, in fact they are still in the process of examining the organs and tissue to understand how these animals age
Currently Dolly the sheep is on display at the National Museum of
