Dolly was the first mammal to be cloned from an adult cell using Somatic cell nuclear transfer. Scientists working at the Roslin Institute in Scotland produced Dolly in 1996, the only lamb born from 277 attempts; it was a major news story around the world.
The nucleus of an udder cell from a six-year-old Finn Dorset white sheep was used to produce dolly. The nucleus contains nearly all the cell's genes. The scientists than injected the cell into an unfertilized egg cell which had had its nucleus removed, and made the cells fuse by using electrical pulses. The unfertilized egg cell came from a Scottish Blackface ewe. Than an embryo developed which was then cultured for six to seven days before implanting it into a surrogate mother, another Scottish Blackface ewe (Roselin Institute 2011).
Dolly was not introduced to the world until all publications were prepared by the researchers (Roselin Institute 2011). When animal carers in the whole world found about dolly and how it was produced, there was concern all over the world of how this will impact the social and ethical aspect of the world. People all around the world panicked even more when news about dolly’s illness also started.
In autumn 2001, the people got even more concerned about dolly’s health and the problems cloning can cause to beings when dolly was diagnosed with arthritis and lung cancer (Roselin Institute 2011). In 2003, Dolly was put to rest because of these problems it was facing. This caused great concern among many different communities.
