Recommended: Risks of human cloning
The term clone is commonly denoted as a genetically identical organism. In today’s world, cloning is thought to only happen to humans in films or shows, but in the real world, the cloning of animals is something that exists today. Animal Cloning became a relative topic among scientists after the success of the first cloned large mammal, Dolly the sheep, using a technique called somatic cell nuclear transfer. The success of cloning a large mammal opened up various possibilities that could come from this. The cloning of animals would be beneficial to both animals and humankind because it would have numerous valuable applications that could be used today and in the future. Animal cloning is beneficial because there are several farming and agricultural applications. Today, …show more content…
The cloning techniques used are considered to be very unreliable and challenging. In the article from the American Journal of Reproductive Immunology, the authors state that “A major limitation of cloning adult farm animals using somatic cell nuclear transfer is the extreme inefficiency of producing live offspring” (Edwards et al 116). The techniques used for animal cloning are thought to be relatively new, in other words, the success of cloning an animal has a very low percent rate of success. In order for the cloning process to be successful, a surrogate mother is needed to for the growth of the clone. According to Riddle, the FDA stated that “surrogate mothers used to grow out clones are ‘at increased risk of adverse health outcomes…’” (112). On the other hand, the FDA also said, “none of these adverse outcomes, however, are unique to cloning” (112). If the cloning of an animal is successful, the clone and the surrogate mother both end up fairly healthy. Animal cloning is still in its early stage and most importantly, scientists are still doing extensive research on the techniques used for animal
Understanding the facts as well as procedures between the many different types of cloning is very crucial. When everything boils down there are three types of cloning known as DNA cloning, therapeutic cloning and reproductive cloning. DNA cloning is the copying of a gene in order to transfer it into another organism which is usually used by farmers in most of their crops. Therapeutic cloning is the use of stem cells used to help take the place of whatever cell is missing which is potentially used to help the ill. Stem cells contain the potential to grow and help replace the genes that are missing in order to fix whatever is genetically wrong with your body or any genes that you may be missing. Reproductive cloning actually produces a living animal from only one parent. The endless possibilities and perhaps hidden motives of using genetic engineering are what divide as well as destroy the scientific community’s hope for passing laws that are towards pro cloning. Many people within soci...
The objective of this essay is to inform the reader(s) about human cloning. I believe that human cloning is morally wrong because one should not have the right to avoid daily responsibilities by getting someone else to handle them. There will be four sections of this paper that will be discussed. Firstly, there is an argumentative section, which will have premises along with a conclusion for an argument made against human cloning. Secondly, an explanation section, which explains how the argument against human cloning obeys the rules for a good argument. Thirdly, an objection section to where there are arguments that violates mine in order to demonstrate how objectors might object to the argument. Lastly, there will be a conclusion where I discuss
Cloning has been in nature for thousands of years, a clone is a living thing made from another consisting of the same DNA. For example identical twins are clones because they have the same DNA but the differ because the twins begin after conception when a zygote, a totipotent stem cell, divides into two, some plants self-pollinate and produce a seed, which in turn, makes plants with the same genetic code (Hyde). According to the Human Genome Project there are three types of cloning, DNA, therapeutic and reproductive; DNA cloning involves transferring DNA from a donor to another organism, therapeutic cloning, known as embryo cloning, involves harvesting stem cells from human embryos to grow new organs for transplant, and last is reproductive cloning which creates a copy of the host (Conger). One of the earliest cloned animals was a sea urchin by Hans Dreisch in the late 1800’s. Unlike Victor Frankenstein, Dreisch’s goal was to prove that genetic material is not lost in cell division, not to create another being, (History of Cloning) stated by Frankenstein “that I might infuse a spark of being into the lifeless thing that lay at my feet.” There are many ways an animal...
Cloning is the creation of an organism that is an exact genetic copy of another. Every single bit of DNA is the same. There are three different types of cloning. Gene cloning produces copies of genes or fragments of DNA, reproductive cloning creates copies of whole animals, and therapeutic cloning builds embryonic stem cells for experiments aimed at creating tissues to replace injured or diseased tissues. In 1997 scientists in Scotland announced the birth of a clone. Its name was Dolly; after the American country singer. She was the clone of an adult female sheep, and the first mammal to ever be cloned successfully. As Dolly matured, she mated with a ram, and gave birth to a lamb showing that clones have the ability to reproduce. Dolly died at the age of six. According to Sheep 101, the life expectancy for a sheep is 10-12 years, but some sheep can live up to 20 years.
Cloning is a procedure of creating genetically indistinguishable organisms through nonsexual means (Devolder 2008). After years of countless research and experimenting, scientists successfully cloned their first mammal using a technique called somatic cell nuclear transfer (SCNT). In Devolder’s paper she states, “Somatic cells are any cells other than the reproductive system cells” (Devolder 2008). Scientists realized they could take fully developed somatic cells from any part of the body and, through the SCNT system, use the cells to make a genetic copy of the cell. This growth in cell research is binding scientists in a race to establish their findings so they could be the first in the finish line. This pressure to be renowned has driven scientists to attempt to control the very natural process of life. Our world is plagued by disease, an increase in population and poverty with limited resources to satisfy the basic needs of mankind, so cloning is often regarded as the solution. Cloning for reproduction and therapy has improved drastically displaying a lot of potential uses but is vastly outweighed with larger risks.
It is essential that human cloning is outlawed. It is salacious to perform, research, and promote these experiments on human subjects; it is neglectful, and shrewd to make the presence of this objective technology legal, let alone obtainable. Not only is human cloning hazardous and illogical, but morally incorrect and greatly dishonorable. The most alarming thought referring to human cloning is that it has the power to alter the foundation, that we as a nation, are assembled upon. What occurs after we take things too far and lose control? What happens when we are no more satisfied in simply seeking education of the physical universe? We will cross the line between natural and synthetic. What will differentiate God from man? Do we have the authorization to change the evolution of life? Science has proven that we can reproduce humans both naturally and unnaturally, but that does not mean that mean we should stop questioning whether or not we should scientifically reproduce humans.
Cloning is a recent innovative technique the National Institute of Health defines as a process employed to produce genetically identical copies of a biological entity. Depending on the purpose for the clone, human health or even human life can be improved or designed respectively. “Somatic cell nuclear transfer (SCNT) is the most common cloning technique. SCNT involves putting the nucleus of a body cell into an egg from which the nucleus has been removed."^1 From this technique, an embryonic cell is activated to produce an animal that is genetically identical to the donor. Today, human cloning still remains as a vision, but because of the success of Dolly, the lamb, researchers are becoming more confident in the ability to produce a genuine
It's been three years since the birth of Dolly, the world's first successfully cloned animal. The announcement of her birth brought about much ado and sparked many debates concerning the morality of cloning. In the three years since Dolly was created, the debate over cloning has swelled and receded, but has never been put to rest. A compelling issue that has come into focus in the past several years is the idea of human cloning. Many scientists believe that it is inevitable because the technology is there, and anything that can be done eventually will be done. They preach the value of human clones, dropping phrases like 'cure for disease' and 'prolonged life' to entice the public into supporting their cause. Though these concepts seem beguiling, the notion of human cloning, when looked at as a whole, has serious repercussions and should not be entertained lightly.
Even though cloning methods have been in use for an extended period of time, the idea of a clone was never thought to be realistic until recently. For thousands of years, humans have been cloning plants through asexual propagation. This is simply the process of stem cutting or grafting a mammal was performed in Switzerland nearly 20 years after the carrot plant where mice cells were cloned. Later, in 1997, Dolly the sheep’s mammary cells were cloned (Lee). This was a major success for science because it was the first time an adult cell was used in which results in a clone of the previous generation of the plant and is still a method used today. It wasn’t until 1958 when modern cloning began with a carrot and in 1964 when scientist John Gurdon started the beginning of animal cell cloning of toad tadpoles. The first successful clone of embryonic cell. After scientists gained a greater knowledge of the process of cloning, they realized that it could possibly be used to benefit the world. In 2001, the first endangered species, the bull gaur, was cloned, and in...
Cloning has become a major issue in our modern world, from moral, ethical, and religious concerns, to the problem of financial and government support. Human cloning is one of the most controversial topics, and because of this, many of the new important discoveries and beneficial technologies have been overlooked and ignored. Reproductive cloning technology may offer many new possibilities, including hope for endangered species, resources for human organ transplants, and answers to questions concerning cancer, inherited diseases, and aging. The research that led up to the ability to clone mammals started more than a century ago. From frogs to mice to sheep to humans, reproductive cloning promises many possibilities.
Spearmann thought of cloning as a way to study cell differentiation. Briggs and King used the technique of nuclear transfer on amphibians and it was successful (Campbell). “Subsequently John Gurdon demonstrated the potential to reprogram differentiated cells by producing adult Xenopus using epithelial cells from developing tadpole intestine as nuclear donors,” says Alberio Campbell. Unfortunately, later studies show that this method of cloning tadpoles didn’t allow them to develop to the adult stage of life (Campbell). “The use of enucleated metaphase II oocytes as recipient cytoplasts proved more successful and in 1986 resulted in the production of live lambs using blastomeres from 8 to 16-cell stage embryos as nuclear donors,” says Campbell. This success in sheep was also used on other mammals such as cattle and swine. There were limitations to the technology. First, the “frequency development was very low”...
Many people say that everyone in the world has a twin. Today, science and technology has the ability to make this myth reality through the process of cloning. I am strongly against cloning for many reasons. People should not utilize cloning because it would destroy individuality and uniqueness, cause overpopulation, animal cruelty, it is against morals and ethics, and it violates many religious beliefs.
In recent years our world has undergone many changes and advancements, cloning is a primary example of this new modernism. On July 5th, 1995, Dolly, the first cloned animal, was created. She was cloned from a six-year-old sheep, making her cells genetically six years old at her creation. However, scientists were amazed to see Dolly live for another six years, until she died early 2005 from a common lung disease found in sheep. This discovery sparked a curiosity for cloning all over the world, however, mankind must answer a question, should cloning be allowed? To answer this question some issues need to be explored. Is cloning morally correct, is it a reliable way to produce life, and should human experimentation be allowed?
Cloning, especially human cloning attracts increasingly more attention after the first mammal cloning animal Dolly born in 1997. Cloning is divided into two categories: therapeutic cloning and reproductive cloning. Therapeutic cloning is more related to tissue level cloning to transplant healthy cells and reproductive cloning is individual level cloning. Thus, the term cloning in this essay is used to describe both individual level and tissue level cloning. Public have different views. Some people support it because of its medical value, yet some people argue that it may bring many safety risks and moral problems. Hence, decisions ought to be made to identify the extent of cloning. Therefore, this essay introduces two major benefits of human cloning on disease therapy and analysis two arguments against it on safety and ethical issues.
First of all, “Australia’s first cloned sheep appeared to be healthy and energetic the day she died, during the autopsy they could not find the cause (Castro, 2005).” There are many risks to cloning and you are seldom able to identify the cause of their death. “More than 90% of cloning attempts fail (Human Genome Program, 2006).” Most cloned animals died mysteriously even before they were born or when they were very young, so there is hardly any information on how clones age. Clones may be born with a normal looking body but may have internal functioning problems. “Cloned animals tend to have more compromised immune function and higher rates of infection, tumor growth, and other disorders (Human Genome Program, 2006).” There are many risks of cloning and a major factor is genetic differences.
