ANIMAL CLONING: SHOULD BE USED AND PRACTICED TO HELP THE HUMAN NATURE

Introduction:
In biology, cloning is the generation of an organism, or even a single cell, with the same genetic material (DNA) of another organism. The process of cloning a plant is relatively simple compared to cloning an animal or a human being. When two animals reproduce and an offspring is born, their genes are a mixture between the DNA of the male and the female. Being a mixture of the two DNAs the offspring cannot be considered as a clone. Nowadays, however, advanced special techniques make it possible to withdraw the DNA from a mother 's egg cell 's and replace it with the DNA extracted from a cell of the individual to be cloned. The male or female donor and the relevant offspring will therefore have the exact same genetic material.

There are three different types of artificial cloning: gene cloning, reproductive cloning and therapeutic cloning. Gene cloning produces copies of genes or segments of DNA. Reproductive cloning produces copies of whole animals. Therapeutic cloning produces embryonic stem cells for experiments. Gene cloning- also known as DNA cloning- is a very different process from reproductive and therapeutic cloning. Reproductive and therapeutic cloning shares many of the same techniques, but are done for different purposes.

Since the birth of Dolly - the first mammal to be cloned- animal cloning is a subject of ethical debates. Whether to use animals for research or new business applications or not is a controversial issue. This study will analyze in details cloning by sketching out a brief history of the cloning of animals. By illustrating the latest news and discovery of the field I will then draw my conclusions on whether cloning should be used and practiced to help the human nature or not.

    Animal Cloning 10/30/14 SEK Group B There are a variety of sheep in the world. Are you familiar with the name “Dolly”? Dolly is the most well-known and the most talked-about sheep in the world. Distinct from other sheep, Dolly was not born through normal mammal reproductions; she was cloned from her mother´s somatic cell, through nuclear transfer. (Wikipedia, 2014) In fact, she is just like a carbon copy of her mother so that they are genetically identical. Obviously, the birth of Dolly…

    Cloning of Animals The cloning of animals is a process in which a single cell is taken from the parent organism and is used to reproduce a genetically identical organism. The animal cloned represents an exact duplicate of its parent in every way, the one exception of that is the original and cloning will not have the same DNA. The first cloning of an animal was of a sheep named Dolly. An instance of animal cloning is, development of twins from a single fertilized egg and asexual reproduction. The…

    Introduction Cloning has been going on in the natural world for thousands of years. A clone is simply one living thing made from another, leading to two organisms with the same set of genes. In that sense, identical twins are clones, because they have identical DNA. Sometimes, plants are self-pollinated, producing seeds and eventually more plants with the same genetic code. Some forests are made entirely of trees originating from one single plant; the original tree spread its roots, which later…

    Andrew McClarren The process and idea of cloning has provoked controversy all over the world for a multitude of reasons. Genetically engineered animals have been studied and created over the last few hundred years. With such a low success rate and high cost associated with it, cloning has failed thus far to be perfected and the large majority of people lack interest in supporting the advancements of genetic engineering. The positive benefits linked with the use of clones tend to be overlooked based…
