Though this is rare it does happen naturally and the two individuals are genetically identical. Artificial embryo twinning copies this separation of a singular embryo into two separate embryos, yet it is done in a laboratory and the embryos are separated manually in a petri dish after the embryo first splits. The two separate embryos are then placed into a surrogate mother where they develop naturally. Somatic cell nuclear transfer produces the same result as artificial embryo twinning, yet it is a different way of cloning. First scientist isolate and egg cell and remove its nucleus.
The birth of these transgenered animals provides a major stepping stone for the cloning of humans. Now groups say they are ready to clone a human being. Controversy over their plan runs high, but scientists believe the technology for human cloning, at least a limited type of cloning for now, is available. A revolution in reproductive biology is now taking place, that provides technical means for cloning humans. Many scientists who work with cloned animals say that the procedure is difficult and dangerous and too ethical to try on humans.
DESIGNER BABIES There have been many social views on the topic of designer babies, which include a scientist point-of-view. Designer babies are those of which parents can make the rash decision to genetically alter their child so that they do not develop the genetic disorders that many of us have today. By using IVF or InVitro Fertilization as the method of altering the genes, doctors have been able to “custom make” unborn babies to portray or eliminate certain characteristics. What is a Designer Baby and How Are They Made? By definition, a “Designer Baby” is a genetically modified, unborn child.
Scientists are now trying to get approval to clone humans or at least parts of them (Eccleston, CNN). All of these clonings have led to much criticism and controversy, but the latest attempt at cloning is that of endangered and possibly already extinct species in hopes of preserving them. This short paper will give a brief description of cloning and the pros and cons of preserving endangered and extinct species via means of cloning. Introduction There are different types of cloning. One type led by researchers at the Human Genome Project entails the copying of genes and parts of chromosomes in order to get enough identical genetic material to do further research, which they believe could help prevent human diseases in the future (Cloning fact sheet).
(Britannica) The process, which was previously described, is the same way that human beings can be cloned. The major misunderstanding is that all someone needs is a sample of DNA to put in this magical machine and a couple days later a fully-grown identical twin is born. The cloning of a human being would be a very difficult, time consuming, and risky venture. It took 277 attempts to clone "Dolly", the sheep born as the first success in cloning an adult mammal. This was achieved in 1996 at the Roslin Institute in Edinburgh, Scotland by a team of British researchers led by Ian Wilmut.
Multiple Source Essay Cloning: What is the Right thing to do? Cloning offers many applications, especially in medicine, however, in spite of the many advantages, many people still consider the idea of human cloning, and the practice of cloning all together to be immoral. This opinion is rarely based on a careful analysis of facts, often only a spontaneous reaction. Cloning technology has potential for doing much good, research in human cloning should continue, although some applications of it may need to be restricted. Cloning is the process of extracting the DNA out of a donor’s cell and implanting this genetic code in another cell in order to grow a being with identical genes, thus virtually duplicating the donor.
But it does force us to ask questions about the way we are using animals with new technology, and the kinds of assumptions we make. To create Dolly (the cloned sheep), Scottish researchers simply took an unfertilized sheep egg and removed its genetic material. They then placed the empty egg in a dish with a cell from an adult sheep's udder, which contained a full complement of the adult sheep's genes. Finally the scientists applied an electric spark, which caused the two cells to fuse and begin dividing. The embryo was then transplanted into the womb of a surrogate mother to grow.
The technique that was made famous by her birth is somatic cell nuclear transfer, in which a cell is placed in a de-nucleated ovum, the two cells fuse and then develop into an embryo” (Science Daily). Clones are the termed referred to when organisms engage in cloning; they are made up of the exact amount of cells and consist of the same genetic material. “Researchers have cloned a wide range of biological materials, including genes, cells, tissues and even entire organisms, such as a sheep” (NHGRI). Cloning all takes control over the same exact DNA schemes for clones. Artificial Copies would be another way to phrase it.
The topical aspects of therapeutic cloning will be closely studied by weighing the pros and cons and gaining a greater understanding of the present scenario. Formally speaking, embryonic cloning is a technique used by researchers and animal breeders to split a single embryo into two or more embryos that will all have the same genetic information. Some more extreme forms of Embryonic or Therapeutic cloning involve the deliberate creation of an identical twin to be destroyed before implantation in order to make replacement tissues. However, these identical twins are usually only six day old embryos, a minuscule collection of cells without a nervous system. Therapeutically, the notion of cloning is medically significant because cloned individuals at the embryonic stage "share the same immune characteristics as each other" (Harris 26).
