Cloning Essay - 3051 Words

Shortly after the announcement that British scientists had successfully cloned a sheep, Dolly, cloning humans has recently become a possibility that seems much more feasible in todays society. The word clone has been applied to cells as well as to organisms, so that a group of cells stemming from a single cell is also called a clone. Usually the members of a clone are identical in their inherited characteristics that is, in their genes except for any differences caused by mutation. Identical twins, for example, who originate by the division of a single fertilized egg, are members of a clone; whereas nonidentical twins, who derive from two separate fertilized eggs, are not clones.

There it was concluded that cloning is not something that can be done as of now, but it is quite a possibil ity for the future. These scientists experimented eagerly in aims of learning how to clone humans. Ruth Macklin of U.S. News amp; World Report writes, quot;Hall and other scientists split single humans embryos into identical copies, a technology that opens a Pandoras box of ethical questions and has sparked a storm of controversy around the worldquot; (http://www.usnews.com/usnews/issue/). They attempted to create seventeen human embryos in a laboratory dish and when it had grown enough, separated them into forty-eight individual cells. Two of the separated cells survived for a few days in the lab developed into new human embryos smaller than the head of a pin and consisting of thirty-two cells each. (http://www.usnews.com/usnews/issue/) Although we cannot clone a human yet, this experiment occurred almost two years ago and triggered almost an ethical emergency. Evidence from these experiments received strange reactions from the public. Ruth Macklin states, quot;Cloning is a radical challenge to the most fundamental laws of biology, so its not unreasonable to be concerned that it might threaten human society and dignity. Yet much of the ethicalShow MoreRelatedCloning Is The Cloning Of Cloning1818 Words   |  8 Pagesorganism. Cloning means an organism is generated genetically identical from an existing organism through non-sexual means. Cloning simply means to make an identical duplication of genes, fragments of DNA molecules, organs, or cells. There are three different types of artificial cloning. They include gene cloning, reproductive cloning, and therapeutic cloning. Gene cloning produces copies of gene segments of DNA. Reproductive cloning produces copies of whole animals. Therapeutic cloning is anotherRead MoreCloning Speech : Cloning And Cloning878 Words   |  4 Pages Prisila Monrroy Mr Bonnet Communications Arts 24 April 2015 Cloning speech Suppose that every prospective parent in the world stopped having children naturally, and instead produced clones of themselves. What would the world be like in another 20 or 30 years? The answer is: much like today. Cloning would only copy the genetic aspects of people who are already here said by Nathan Myhrvold. Cloning is an issue now and will be in the in the future,animals are cloned all the time.DoesRead MoreThe Cloning Of Human Cloning1006 Words   |  5 PagesTwins? Or is it clones? It has been known that identical twins are natural clones. 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 MoreThe Cloning Of Human Cloning1332 Words   |  6 PagesCloning Science today is developing at warp speed. We have the potential to do many things, which include the cloning of actual humans and animals. The question no longer seems to be if we will clone humans, but when? Somewhere, sometime, a human clone will be born. This fact has exploded the world into a global debate. Will large armies of soldiers be raised to fight our wars? Or perhaps we will create a race of slaves to do our dirty work. Cloning is becoming more credible and concrete idea ratherRead MoreThe Power Of Cloning : Cloning868 Words   |  4 PagesThe Power of cloning Cloning can occur naturally, but this mainly happens with bacteria. Bacteria does this thing that is called asexual reproduction and causes it to reproduce the exact same copy as before. â€Å"When they clone an animal, first they take skin cells from the animal to be cloned. Then, they take an unfertilized egg from the adult female of the same species and remove the nucleus of the egg which contains the other half of the DNA, leaving the mothers egg empty. After that they put theRead MoreThe Cloning Of Human Cloning1774 Words   |  8 PagesIntroduction- Cloning is defined as two organisms having identical genetic DNA and has been around since the early 1800s. When people think of the word ‘cloning’ many think of Dolly the sheep; however, the first organism to ever be cloned was a sea urchin in 1885. When scientists created Dolly, they took a cell from the mammary gland from an adult Finn Dorset sheep and an egg cell from a Scottish blackhead sheep. Dolly’s whi te face was the first sign that she was genetically modified because if sheRead MoreCloning712 Words   |  3 PagesCloning 1. What should Dr. Smith do? I think that with such minimal overall research done in the entire cloning industry and no research done with a human being the variable, it is not a wise decision for Dr. Smith to proceed with cloning the body cell of Lucy. Although I don’t think that any further damage (besides death) could happen to Lucy, if something terrible happens or if the procedure does go well and then Lucy becomes ill or something else goes wrong with the cloning in the longRead MoreThe Cloning Of Cloning For Medical Services1586 Words   |  7 PagesThe Ethicality of Cloning Cloning the latest process that could change the way we look at our environment, and the step to take us to lose what makes us unique and unparalleled. Cloning is the process of producing a genetically identical individual to the original. There are three types of cloning: gene cloning, reproductive cloning and therapeutic cloning. The disadvantages of cloning is that there had been many attempts at cloning and the results have been numerous deformations and abnormalitiesRead MoreCloning And Its Implications On Human Cloning1497 Words   |  6 PagesCloning and Its Sociobiological Implications Picture this: walking down a street and seeing someone who looks exactly like you. They do the same things as you, act the same way you do, and are exactly alike in several ways. But have people ever considered the consequences of human cloning if it becomes permitted? Human cloning might seem like something out of a science-fiction novel, but it may someday be possible with advances in science and technology.

These two organisms are the same identical replica of each other. In the past, cloning has taken place naturally. For instance, a couple who naturally conceived and gave birth to identical twins or triplets. Today, science and technology has been introduced to where cloning can intentionally be done. Some people
