Dolly changed modern science and our ideas about biology in many ways. For most scientists the birth of Dolly overturned the assumption that the whole process of cell differentiation was irreversible. Life is started as a fertilized egg and the cell divides and multiplies and by the time we are born, there are maybe 200 different cell types, each differentiated into a particular role that is determined by the proportion of active genes within the cell. Many Scientists assumed that this process of differentiation was permanent. What Dolly demonstrated was that it is possible to take a differentiated cell and reactivate all its silent genes making it behave as though it were a recently fertilized egg.
According to an interview in the London Times, Professor Sir Ian Wilmut said he believes that human organs can be cloned ethically because now cells can be cloned without an embryo. He said that cells could now be "reprogammed", meaning healthy cells could be inserted into the brain to cure diseases such as motor neuron disease and Parkinson's. There are many ways to help people through new cells. New cells can replace damaged tissue …show more content…
Everyone was interested in this new clone (the first clone of a mammal) and it excited a lot of public imagination. The idea that humans could be cloned just from a single skin cell was unimaginable. Many science fiction movies and books are about cloning and the idea that your identical twin could be walking around somewhere is both exiting and disconcerting. As of now this is quite impossible because the process of Nuclear transfer is highly ineffective and a lot of cells were discarded before one became dolly. According to the Roslin Institute's website many countries including the United States strictly ban cloning of humans. So unless some highly advanced aliens land on earth and produce clones of us to take home, we are safe from being cloned. For
