Re oceanrch Paper: Animal CloningCloning has been outlet on in the natural world for thousands of years. A copy is simply one living thing made from other living thing with the exact like DNA. Identical fit are considered clones because they have the same DNA. An earthworm that is cut in half will regenerate its missing split creating two identical earthworms, two worms, same exact genes. A tree is planted and it spreads its roots, new trees develop and grow from these roots, in the first place long an broad(a) forest is produced originating from that one tree. Thats an entire forest of naturally cloned trees. So cloning in itself is zip fastener new, but the scientific cloning of animals is very new in comparison to the cloning going on in nature.
In the late 1800s Hans Dreisch was the first person to clone an animal. It wasnt
done through some fancy, high tech regularity obviously, he simply took a two carreled embryo of a sea urchin and shook it in a beaker filled with sea water until the two cells separated. The two cells grew independently from one another(prenominal) and eventually formed two separate whole sea urchins. In 1902 Hans Spemman performed a similar experiment apply salamanders, his results were the same as Dreischs.



For nearly fifty years however thither were no major advances in cloning. In 1951, a mathematical group of scientists in Philadelphia successfully cloned a frog embryo using Somatic Cell Nuclear Transfer. Somatic cell thermonuclear transfer is the transfer of the nucleus from a embodied cell to an formal cell. A somatic cell is any cell of the body other than a sex cell, for example, a production line or skin cell. In this process, the nucleus of a somatic cell is removed and inserted into an unfertilized egg that has had its nucleus removed. The egg with its donated nucleus is then nurtured and divides until it becomes an embryo. The embryo is then placed deep down a surrogate mother and develops inside the surrogate.
