Genetically Identical Identical Twins
1,390 wordsOf all the terms coined by scientists which have entered popular vocabulary, 'clone' has become one of the more emotive. Strictly speaking a clone refers to one or more offspring derived from a single ancestor, whose genetic composition is identical to that of the ancestor. No sex is involved in the production of clones, and since sex is the normal means by which new genetic material is introduced during procreation, clones have no choice but to have the same genes as their single parent. In the...

Cloning Of Human Beings Cloning Of Humans
2,643 wordsCloning, the process of? Manipulating a cell from an animal so that it grows into an exact duplicate of that animal is the forbidden fruit of biology. ? (Begley 54). The word? clone? , derived from the Greek word? Know? , meaning twig or slip, refers to asexual reproduction. Also known as vegetative reproduction. Cloning became known to the public about 30 years ago. This idea of cloning about his time resulted in an experiment of the successful asexual reproduction. This experiment took place i...

Bioethics Advisory Commission National Bioethics Advisory
1,344 wordsOn February 24, 1997, the scientists at the Roslin Institute in Edinburg, Scotland announced their success in cloning an adult mammal for the first time. The cloned sheep was named Dolly. She was the first animal cloned from a cell taken from an adult. It was an accomplishment than science had declared impossible. In June, 1997, the National Bioethics Advisory Commission issued its recommendation that a ban be placed on all efforts to create a child through cloning or somatic cell nuclear transf...

Human Cloning Research Ian Wilmut
1,910 wordsAccording to the American Heritage Dictionary, cloning is to make multiple identical copies of a DNA sequence, to reproduce or propagate asexually. A clone is a group of genetically identical cells descended from a single common ancestor, such as a bacterial colony whose members arose from a single original cell as a result of binary fission. The process of cloning has challenged every mind in the world. Is it right to make a human being from the cells of another? In this paper I plan to discuss...

Nuclear Transfer Udder Cell
528 wordsCLONING SPECIAL REPORDollys mixture Clones are not the perfect replicas we thought. By Philip Cohen Dolly the sheep does not have precisely the same genetic make-up as the adult sheep from which she was cloned. A study shows that the genes in her mitochondria the powerhouses of cells came from another sheep involved in the experiment. The result leaves scientists wondering: exactly how similar are Dolly and her genetic twin? In a cloning technique called nuclear transfer, a donor cell is fused w...
