Bio Engineering, Cloning Dolly The Sheep

Bio engineering is one of the technological fields that kept on developing at a very fast pace in the last years. People can nowadays do with the help of bioengineering things that they could never dream of and cloning is one of them. Cloning is certainly an aspect of bioengineering that carries along several controversial issues but it is also the step forward the humanity needed in order to keep up with the progress and diversification of medical conditions. For instance, there is much hope in that cloning human embryos for the sole purpose of extracting stem cells can cure diseases that have been previously known as incurable. Here one can read more about how cloning started and in particular about the genetic cloning of Dolly the sheep.

Dolly is perhaps one of the best known sheep in the world because it is was the first ever cloned mammal who was moreover a success showing that science can actually work in this area. Dolly the sheep was cloned from an adult cell in 1996, in Scotland where she lived until her death in 2003. One can still see her stuffed remains in the Edinburgh’s Royal Museum, the evidence that she actually existed being conserved for the many generations to come. The cloning of Dolly was more than significant and it attracted the attention of different categories of people from different parts of the world. Dolly demonstrated that a new organism can be created from one specific adult cell.

Cloning Dolly also pointed out that successful cloning is still something that must be worked on. She was the only successfully cloned organism in 237 eggs that has been used to create nearly 30 embryos. Three lambs were created but only one had survived, Dolly. Her death had also outlined the possible genetic mutations that have been associated in the end to her death.
