...Human Cloning comes with two dangerous processes, reproductive cloning (the creating of a new organism) and the therapeutic cloning (the creation of a new tissues or “other biological products”) which affects the ethics of human society. Scientists perceive cloning benefits all men and women, while religious leaders stress the idea of cloning to be an unethical process. Although human cloning serves as an aid to the children and parents with conflicts, cloning is completely unacceptable to convey human life as a product. Humans reproductively and therapeutically give the idea of people becoming a product rather than a living being. Siedler emphasizes that “reproductive cloning could also represent an enormous step in direction of transforming human procreation into human manufacture” (Siedler 91-92). In other words, reproductive cloning will create a world full of dolls that will remove every trace of living beings. Though it is hard to believe the world becoming a doll house for each family or community, it has come to a conclusion that the ability of cloning and “creating children” is questioning every person, “what does it mean to be a human?” (Yount 114). If it was not bad enough for this world to describe some of the people to be looked upon as nothing but a thing, cloning pushes the idea to a whole new level. “By opening the door to many things such as manipulation,” Yount states, as she desperately explains the fear in cloning, “of wanting to be someone else, it can treat...

...The subject of human cloning is a complex issue, and with complex issues there are a variety of different opinions on the subject. Allowing general access to cloning should not be allowed as it will cause a social and ethical controversy. However, limiting it to only medical access such as life threatening situations is another way to strengthen the limitations. Cloning is the process of creating a new organism by copying genetic information from a single “parent” organism. In a way, a clone is a time delayed twin. It has the exact DNA of the original person it was copied from. There are two different methods of human cloning, therapeutic and reproductive. Both processes use nuclear transfer, the nucleus of an egg is removed and replaced...

...There are three types of cloning: reproductive cloning, gene cloning, and therapeutic cloning. Reproductive cloning involves creating an exact copy of an organism. An example of this is Dolly the sheep, the first mammal to be cloned. Gene cloning is the duplication of segments of DNA (which contain specific genes). Scientists often use gene cloning for research; for example, the creation of a plasmid with specific traits. Therapeutic cloning focuses on using a cloned embryo to derive embryonic stem cells for the treatment of different diseases. Both therapeutic cloning and reproductive cloning are done through the same process, somatic cell nuclear transfer (SCNT). A somatic cell is a body cell (basically any other cell besides a sperm or egg cell). SCNT typically uses skin cells. The nucleus of a skin cell is removed and injected into an egg cell (that has had the nucleus removed). The egg cell with the nucleus of the skin cell will act like a newly fertilized egg. For the purpose of reproductive cloning, the egg can be implanted in the uterus of a surrogate...

...A. Byrne ¡ John B. Gurdon Commentary on human cloning Introduction Human cloning refers to the production of genetically identical humans. This cloning is possible via either ‘‘embryo splitting’’ or ‘‘nuclear transfer’’. Embryo splitting involves the separation of an early human embryo into two or more parts. Each of these parts has the potential to develop into a blastocyst (late embryo), which, if implanted, can develop into a child. This is how genetically identical monozygotic twins are created. Artificial embryo splitting has been successfully implemented in various mammals including sheep (Willadsen, 1981), cows (Willadsen, 1989), mice (Agrawal and Polge, 1989) and monkeys (Chan et al., 2000), but has been performed only to the pre-implantation stages in humans (Hall et al., 1993). Recently the American Society for Reproductive Medicine declared that human cloning by artificial embryo splitting was an ethical procedure to increase the number of implantable human blastocysts used in certain infertility treatments (ASRM, 2000). However, embryo splitting can produce only a limited number of cloned individuals as the early embryo can be separated only a limited number of times, and the procedure is not able to produce a ‘‘clone’’ of an adult that already exists. The other method for producing cloned humans, nuclear transfer, does not suffer from these limitations, and the rest of this article will focus on human cloning achieved via this technique. Nuclear transfer (or...

...material, and making an exact copy, is known as cloning. A revolutionary advancement, we are now capable of achieving with the technology and knowledge obtainable to us. When it comes to cloning, there is three types; therapeutic/research, reproductive human cloning and reproductive animal cloning. The mere thought of cloning has always been science fiction to me, something you only see in movies. Now that i'm faced to ponder whether or not any kind of cloning should be permitted. I believe that, just because something can be done, doesn't mean it should be done. I urge you to please consider all the moral and ethical values we have as people, when its comes to permitting any type of cloning. As the outcomes, can be great in positive and negative gravity. The possibilities that come with therapeutic cloning, are enough to make...

...helix structure by James Watson and Francis Crick in 1953. Surely they would have never imagined what scientists can do with human DNA today. Cloning, gene therapy, stem cell research, and genetically modified foods all began with the discovery of DNA and probably would have been unimaginable in anyone’s eyes in the 1800’s. But scientist’s today are manipulating genes and DNA in an effort to prevent disease, cure disease, and feed the world. History was made on July 5, 1996 when Dolly the sheep was born. She was the first mammal to be cloned from adult DNA. By splitting two-cell embryos apart, scientists were able to produce two genetically identical organisms. Cloning is a process of making genetically identical organisms through non-sexual means. There are three types of cloning, DNA cloning, reproductive cloning, and therapeutic cloning. DNA (or molecular) cloning consists of removing a small piece of the DNA strand and uniting it with a plasmid which reproduces itself to create multiple copies of the same DNA code. The copied DNA can then be grown in a suitable host cell where the recombinant vector can then be reproduced along with the host cell DNA. DNA cloning is typically used in biological experiments and technological applications where large scale protein production is needed. (NRC, 2002) Reproductive cloning is used to create and animal with the same DNA as an existing animal. In a process called somatic cell nuclear transfer the DNA information...

...Even though there are many ways that cloning can help to improve lives, there are still some people who worry that it could do the opposite. This sparks a debate over the moral and legal issues of cloning, and how it could deprive humans of their lives in certain ways of cloning such as reproductive cloning. They worry that embryos and fetus’ will be grown for their stem cells, which is essential for cloning. "Several countries have enacted legislation to ban human cloning.”(Cloning) as well as “several states have passed their own laws prohibiting such research.”(Cloning) This “raises a number of challenging scientific, legal, philosophical, and ethical issues.”(Cloning) These examples show multiple Government’s views on cloning.

...produced by cloning methods and was born to a surrogate mother (“Cloning Fact Sheet”). The methods used to clone Dolly were once considered to be biologically impossible (Wilmut and Highfield 12). Thus, once Dolly’s birth was announced to the rest of the world, an immediate debate over the ethics of cloning began. In particular, reproductive cloning was widely discussed because it could possibly be accomplished through somatic cell nuclear transfer to clone entire humans (“Cloning Fact Sheet”). For medical, social, religious, and political reasons, there are both proponents and opponents of reproductive human cloning and its ethics. Currently, the best way to deal with reproductive cloning is to ban its use because there are many negative consequences that could arise from using cloning technology. There are two different types of human cloning: therapeutic cloning and reproductive cloning. The goal of the former is to obtain stem cells from embryos that can be used to study the growth of the human body and to find possible cures and treatments for various diseases (“Cloning Fact Sheet”). The purpose of the latter, on the other hand, is to create a whole human being through cloning. Specifically, reproductive cloning is done using somatic cell nuclear transfer and can theoretically produce a human that has the same exact nuclear DNA as another individual. Currently, though, this technology has only been used to clone animals and has not yet been successful in cloning humans (“Cloning...

...The Next Generation of Cloning Hundreds of countries around the world are scrambling to ban human cloning, but scientists are convinced cloning can be useful in the near future. Cloning is making a replica of an organism or a cell, a copy of a human or mammal and making two or more of them. There have been a majority of people that have appealed to cloning and whether human beings should not be cloned nor should cloning be used. There has been many reasons for whether cloning should be allowed or not allowed. The heated debate over human cloning has changed how society views human life. This issue is dividing American society. Many argue that cloning is risky, unsafe, and can be harmful to mankind. Others contend cloning to be beneficial and...

...HUMAN CLONING Human Cloning Human Cloning One of the most controversial topics around the world today is human cloning. Knowledge rush defined cloning as “the creation of a genetically identical copy of an existing human or growing cloned tissue from that individual.” Human cloning is also referred to as artificial human cloning. Cloning efforts date back to the 1800s with the attempts to clone sea urchins and frogs. As of today, human cloning has not been perfected or deemed safe. Human cloning should not be legalized due to the high possibility of wiping out the entire population, overcrowding the entire population and the many ethical and medical issues. More advanced research, studies and experiments are needed before human cloning can become a reality. Then we have therapeutic and reproductive cloning. Therapeutic cloning is defined by med terms as “a procedure when cells (typically from the skin), are taken from patients and then inserted into a fertilized egg whose nucleus has been removed.” The stem cells that are extracted are used to grow tissue that could possibly be a genetic match and treat disorders like diabetes, Alzheimer’s and Parkinson’s disease. Keep in mind that this is not 100% accurate and that it’s a big part of the bioethical controversy. Developing cures is a huge one. The effort to find cures for illnesses will become extinct because every scientist and doctor will be too focused on cloning and looking out for themselves. Then...

...\While the history of cloning is relatively short, understanding how cloning came about is important to understanding the greater debate surrounding cloning. At the Roslin Institute in Edinburgh, Scotland, in July 1996, scientists produced the first animal cloned from an adult cell. Dolly the sheep was born early in 1997, shocking the scientific community and the world. Dolly was created through a process called cell nuclear replacement. A mammary cell of a six-year-old white Welsh Mountain sheep was transferred into the egg shell of a Scottish Blackface ewe (Calhoun Cash 2). Since Dolly’s birth, other species have been cloned as well, including mice, cattle, pigs, goats, rabbits, and cats (Calhoun Cash 2). Dolly’s birth and the development...

... CLONING Cloning is a very controversial issue that has undergone severe criticism and debate ever since the technology was invented in 1983 and probably will not have a final end to it.So what is cloning? And why are there many controversies and concerns arising after the invention of this technology? Cloning is the process of generating a genetically identical copy of a cell or an organism. Cloning is a controversial issue because of the social and physiological risks associated with it. Opponents of cloning have concerns that technology is not yet developed enough to be safe, that it could be prone to abuse (leading to the generation of humans from whom organs and tissues would be harvested), and have concerns about how cloned individuals could integrate with families and with society at large. Religious groups are divided, with some opposing the technology as usurping God's place and, to the extent embryos are used, destroying a human life; others support therapeutic cloning's potential life-saving benefits. There are different types of artificial cloning and these are gene cloning, reproductive cloning and therapeutic cloning. Gene cloning produces copies of genes or segments of DNA. Reproductive cloning produces copies of whole animals. Different scientists have different reasons and goal unto why they want to clone and the reasons often directly correlate with the type of cloning to be conducted. For instance Rael who is a...

...What is Cloning? Clones are organisms that are exact genetic copies. Every single bit of their DNA is identical. Clones can happen naturally—identical twins are just one of many examples. Or they can be made in the lab. Below, find out how natural identical twins are similar to and different from clones made through modern cloning technologies. How Is Cloning Done? Many people first heard of cloning when Dolly the Sheep showed up on the scene in 1997. Artificial cloning technologies have been around for much longer than Dolly, though. There are two ways to make an exact genetic copy of an organism in a lab: artificial embryo twinning and somatic cell nuclear transfer. 1. Artificial Embryo Twinning Artificial embryo twinning is a relatively low-tech way to make clones. As the name suggests, this technique mimics the natural process that creates identical twins. In nature, twins form very early in development when the embryo splits in two. Twinning happens in the first days after egg and sperm join, while the embryo is made of just a small number of unspecialized cells. Each half of the embryo continues dividing on its own, ultimately developing into separate, complete individuals. Since they developed from the same fertilized egg, the resulting individuals are genetically identical. Artificial embryo twinning uses the same approach, but it is carried out in a Petri dish instead of inside the mother. A very early embryo is separated into individual cells, which are allowed...

...Two of Us: Cloning Cloning didn’t make a significant impact in culture or science until the first mammal was cloned in 1997. Cloning is the process in which an exact genetic copy of an organism is made. The first successful cloning was of Dolly the sheep. Though this was a huge stride for the scientific community, there has been many public riots against this action. Over the years scientists have researched and there has been several successful cloned animals; however, there have been many unsuccessful clonings. Throughout its history, cloning has overcome many obstacles. Scientists have discovered three types of cloning, anyhow, it is still not well received in society today. The founders of modern genetics, took the first steps in re-evaluating the previous theories used for cloning. August Weismann, Professor of Zoology and Comparative Anatomy at the University of Freiburg, proposed that cells can be manipulated by similar genetic organisms (Beale 2). Soon after Weismann’s theory was given public attention, two other scientists tried experimenting with his theory on manipulating similar organisms. During this time of trial and error, most of the animals used were small, such as: frogs, bird eggs, mice, and...

...eting debates about the numerous possibilities cloning had for our world. In recent years, due to sports injuries and other battle wounds, these possibilities have become increasingly personal for me, even as the technology and the debates have rapidly advanced. It seems that since the discovery of fire humanity has attempted to imitate and manipulate phenomena that nature has had billions of years to develop and perfect. Cloning is a perfect example of such attempts. In nature, cloning is the process by which genetically identical organisms are produced by way of asexual reproduction. With some success, scientists have been working on ways to reproduce this phenomenon through biotechnology, in a laboratory setting. In biotechnology, cloning refers to the process used to create copies of DNA, cells, or entire organisms. Each of these forms of cloning will be described in this paper, which will then explore the issues surrounding cloning from biological, technological and public health standpoints. Molecular cloning, or DNA cloning, is the process of making multiple copies of an isolated sequence of DNA fragments (Strachan & Read, 1999). This form of cloning is most often used in biological research, but is also used in more practical applications such as genetic profiling and protein production. In practice, techniques such as this are often used producing vaccines and researching cures to common ailments. Molecular cloning isolates a desired segment of a DNA and links t...
