Cloning Case

Cloning

For many decades cloning was considered a ridiculous and impossible idea that could only emerge in Sci- fi novels. It was idea that was found impossible by most scientists and it was a goal that was nearly impossible to achieve. The date February the 22nd 1997 will always be remembered as the day where Dr. Ian Helmut changed the face of history. Cloning developed from a silly dream to a reality. This is a date one an average looking sheep Dolly was presented to the public. What seemed to be a normal sheep was anything far from average. Dolly was the first ever clone of a mammal (of her own biological mother).

However, since it was developed cloning has been an ethical and moral issue. On the one hand, it could help in the development of new technologies and it could even help in discovering new cures for disease. On the other hand, cloning is a very dangerous technology that in the wrong hand could do a lot of harm. It was a risk that people are still uncertain to take or not.

To judge this topic one must understand the concept of cloning so the question is what exactly is cloning??!

"Cloning is the process of creating an identical copy of an original. It is a single cell or multi-cellular organism that is genetically identical to another living organism. Cloning can also occur when two genetically identical individuals are produced by accident like identical twins, but in common scientific language the clone is an identical copy by some conscious design. Cloning an organism is to create a new organism with the same genetic information as an existing one. This can involve the transfer of a cell nuclear in which the nucleus is removed from an egg cell and replaced with a nucleus extracted from a cell of the organism to be cloned" Simply, cloning is creating anything which is an exact copy from an original with the exact same DNA. As we know the DNA of every living being is different and two exact DNA s are never found. Cloning however could enable us to create an exact copy from any living being. To understand cloning further we need to analyze the history of cloning and how it was developed.

First, we have to admit that cloning actually exists in nature as identical twins could be referred to as clones as they posses the same DNA. The earliest attempt of cloning was in the early 1800s when a scientist called Hans Dreisch tried to create identical animals and it was claimed that he succeeded in cloning sea urchin. Also, 1902 Hans Spemmann tried to clone a salamander through its embryo and he successfully created two identical salamanders. Those were actually the first two experiments in the unknown field of cloning. The first actual success next came in 1951 when scientists working in Philadelphia tried to clone the embryo of a frog. They replaced the nucleus from an unfertilized egg cell
