What is cloning?If we refer to the field of genetic engineering, cloning is to isolate and multiply in a test tube a particular gene or, in general, a piece of DNA. However, Dolly is not the product of genetic engineering. In the context of what we mean, mean get an individual clone from a cell or a nucleus from another individual.

Beyond Dolly promising future for many commercial applications of cloning technology. Commercial applications such as the creation of herds of transgenic animals. Tran Genesis is the ability of adding new genes to an animal, as it has in Norway Vajta and Jørgensen by inserting human genetic material for the hereditary form of Alzheimer’s disease in cloned piglets.

Dolly was not the first cloned mammal. That honor went to two cousins of Dolly – Morag and Megan. Researchers at the Roslin Institute announced the birth of Megan and Morag in May 1996. Cloning twins, which started with an embryo of nine days old, who had a hundred cells. The first cells of the embryo has a property called totipotency, the ability to isolate any cell type, but these cells are still identical to their parents before they have differentiated. The research team led by Ian Wilmut, the totipotent cell divided embryos in culture dishes, thousands of cells in less than a week.
