A Science†¦show more content†¦That will also be true if the egg comes from the nucleus donor’s mother, because mitochondria are inherited maternally. Multiple clones might also be produced by transferring identical nuclei to eggs from a single donor. If the somatic cell nucleus and the egg come from different individuals, they will not be identical to the nuclear donor because the clones will have somewhat different mitochondrial genes. †¢ Cloning by embryo splitting. This procedure begins with in vitro fertilization (IVF): the union outside the woman’s body of a sperm and an egg to generate a zygote. The zygote (from here onwards also called an embryo) divides into two and then four identical cells. At this stage, the cells can be separated and allowed to develop into separate but identical blastocysts, which can then be implanted in a uterus. The limited developmental potential of the cells means that the procedure cannot be repeated, so embryo splitting can yield only two identical mice and probably no more than four identical humans. The DNA in embryo splitting is contributed by germ cells from two individuals—the mother who contributed the egg and the father who contributed the sperm. Thus, the embryos, like those formed naturally or by standard IVF, have two parents. Their mitochondrial DNA is identical. Because this method of cloning is identical with the natural formation of monozygotic twins and, in rare cases, even quadruplets, it is not discussed in detail in thisShow MoreRelatedCloning Dolly the Sheep3788 Words   |  16 PagesThe Cloning of Dolly the Sheep 3 The Human Cloning 4 Nature4 Studies4 Process 5 Arguments6 Official Catholic Church Teaching7 Church says â€Å"No† to Human Cloning7 What Does the Bible say about Cloning?8 Conclusion9 Response to the teaching of the Catholic Church9 Moral Judgment9 Reflection11 Reference12 The Cloning of Dolly the Sheep Focusing on the Case A major scientific achievement was done at the Roslin Institute because the cloning of a sheep was successful.

It indicated that nuclear reprogramming can completely re-activate genes after being inactivated during tissue differentiation. There is enormous potential application in cloning by nuclear transfer using mammalian somatic cells However, somatic cloning used in producing live clones have resulted in defects and high fetal mortality rates. Therefore, the cloningRead MoreCloning: The Story and Impact of Dolly the Sheep762 Words   |  3 PagesCloning: The Story and Impact of Dolly the Sheep Dolly the sheep is one of the biggest breakthroughs for cloning and scientific history. Dolly was the first sheep cloned which created with a replicated DNA. Dolly the Sheep was created by Ian Wilmut and scientists from the Roslin Institute of University of Edinburgh in Sweden. The name†Dolly† comes from the country star Dolly Parton . Dolly the sheep sent shock waves through the world when the news was released 7 months after her birthRead MoreReproductive and Therapeutic Cloning: Dolly The Sheep1468 Words   |  6 PagesTherapeutic cloning and the processes that happen in order for cloning to occur. DNA Cloning occurs when the DNA cell is replicated, an organisms DNA is taken and placed in a Vector also known as plasmid. This self-replicating cell will then create copies of the DNA code. After being placed into a foreign host cell that is suitable for the DNA the cell will then reproduced. Reproductive cloning in some aspects of the developing stages is si milar but is still completely different. Reproductive cloning is theRead MoreThe Problem Of Human Cloning1034 Words   |  5 PagesThroughout this paper, I will be talking about the topic of human cloning. However, there are many who have concluded to different definitions. To clarify, and use a specific definition, the American Medical Association defines the method of cloning as the production of genetically identical organisms. In summary, the process of cloning is producing a child, with completely identical genes, or parent. It is important to realize that cloning does not necessarily produce an exact replica of the individualRead MoreGenetic Engineering : Medical Perfection Or Playing God1280 Words   |  6 PagesThesis Statement â€Å"Genetic engineering differs from cloning in key ways. Whereas cloning produces genetically exact copies of organisms, genetic engineering refers to processes in which scientists manipulate genes to create purposefully different versions of organisms—and, in some cases, entirely new living things†, duplication of genetic cells is known as human cloning. Development of genetic engineering biotechnologies undermines the natural autonomy of life. Does genetic engineering interfereRead MorePros And Cons Of Cloning1109 Words   |  5 PagesWhat is Cloning? Cloning is a number of processes that are used to create genetically identical copies of an organism. Researchers have cloned a number of biological materials, such as genes, cells, tissues and whole organisms, including sheep s and horses. Cloning can happen naturally in identical twins, but it can also be done in a lab. (Cloning Fact Sheet). Pros: . Parents with no eggs and sperm can create children that are genetically related to them. . Endangered plants and animals canRead MorePros And Cons Of Cloning1106 Words   |  5 PagesCloning is a number of processes that are used to create genetically identical copies of an organism.

The question is, what is cloning? Cloning is the process of making a genetically identical organism through the use of a DNA sample. There are three different types of artificial cloning: gene cloning, reproductive cloning and therapeutic cloning. Dolly, the sheep, was the first mammal to have been successfully cloned from an adult cell. There is a specific procedure that has to be followed for a clone to be madeRead MoreCloning Right or Wrong? Essay1336 Words   |  6 PagesCloning Right or Wrong? Have you ever heard of cloning before? Well it has a lot of ups and its downs, many people are against it and many are for it? In my paper you will hear and of the good things and the bad things that happen in cloning and you can decide if you think it is right or wrong. History When I looked up the definition for cloning on www.m-w .com it stated that cloning is to propagate a clone from or to make a copy of. A book on cloning that I read stated that cloning is genetically
