Recommended: Cloning humans benefits
Many people believe cloning is unethical and unusful. They believe that it should not be practiced, because it infringes upon their beliefs. They see cloning as a last resort and do not trust the science of cloning. “Several governments have considered or enacted legislation to slow down, limit or ban cloning experiments outright” (Freudenrich 5). Many people think that cloning a species is a very unideal situation. However the many benefits of cloning far outway the few disadvantages. Cloning endangered species is beneficial to saving most species around the world, in countries like the United States and China, from extinction.
One of the oft-heard arguments against reproductive cloning is that humans should not be interfering with nature or "playing god". When it comes to endangered species, I am not persuaded. For the past few millennia, and particularly the past century, humans have been the driving force behind the overwhelming majority of species' extinctions. In other words, we have already been very busy playing god.(Nicholls)

This is explained by Craig Freudenrich. He discusses this on the website HowStuffWorks. Freudenrich tells of how Ian Wilmut and his colleagues successfully cloned Dolly the sheep at the Roslin Institute in Midlothian, Scotland. Dolly the sheep was the world's first successfully cloned mammal, cloned from an adult somatic cell. He writes how after Dolly, scientist have been cloning animals like cows and mice. “They rely on transplanting the genetic information from a specialized cell into an unfertilized egg cell, whose genetic information has been destroyed or physically removed.” (How Cloning Works) This information is very enlightening to anyone who questions how cloning works. Furthermore it secures the information needed to inform the general public of what they need to know to have a responsible and appropriate
Humans have driven many animals extinct, but should we bring them back is the question. Geneticists, biologists, conservationists and ethicists gathered to discuss the controversies. Some people say in doing this we are playing God, while others say we did by killing them. Other scientist say that it may be beneficial because it will add biodiversity, and medicinal properties back to the ecosystem. It is only possible to bring species back from around 10 thousand years ago. Recently scientists have vastly improved the cloning process. We can now coax adult animal cells into any type of cell, including eggs and sperm, then manipulating them into full-fledged embryos, which has led to the ideas and developments of reviving many other species including mammoths, frogs and
Before Dolly the cloned sheep made news headlines, the same researchers had only the year before raised seven other sheep from oocytes whose nuclei had been replaced with nuclei from either fetal or embryonic tissue.1 This created a minor stir as this is the "first report to [their] knowledge, of live mammalian offspring following nuclear transfer from an established cell line."1 The implications of this is that they have provided techniques to analyze and modify gene functions in sheep (By providing clones of the same sheep).1 The key to their success is the "serum starvation" that the donor cell undergoes, to force the donor cell into a 'quiescent' state, so that it is not replicating its DNA or dividing. This possibly makes the nucleus more susceptible to re-programming by the recipient egg cell.
Human and animal cloning is still a debatable issue. People believe that cloning is playing God, just as Victor Frankenstein did when he created the Monster. While Victor Frankenstein’s creation ended in catastrophe, cloning’s seemly innocent side effects can still disrupt and alter the entire world.
But on the contrary, many scientists believe that cloning can be such a positive achievement, not only for medical purposes, but for fighting extinction. For example, what if they could clone many of the endangered species that exist today? There are very few hundred of many beautiful animals that if something isn’t done to save them, they will be extinct in a few years. So if scientists could successfully clone and create these endangered species, although it would still depend on the clone maturing correctly and being able to reproduce successfully, it could be a great
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
The topic I chose was cloning, but I will be focusing on Human Cloning. Dolly the sheep was the first mammal to be created using cloning technology in 1997. With the birth of Dolly the sheep it had raise of a possibility of one day being able to clone human. It took 277 times to create dolly the sheep although it suffers from arthritis and premature aging. In December 2002, a religious group of Raelin claimed that a human baby was cloned but it had not been scientifically confirmed. In 1962 John Gurdon claimed to have cloned South African frogs from the nucleus differentiated adult intestinal cells. In 1964, F.E Stewart grew a complete carrot plant using the carrot root cells and to prove that cell cloning was possible. Francis Crick and James Watson were the first pioneers to discover double helix structure of DNA in 1953. It increased the scientific research of learning about human genetic codes and discovers the possibility of cloning. According to Vos (2004), “In 1984, Steen Willadsun cloned a sheep from embryo cells, which were the predecessor to Dolly’s method of cloning.” In 2002 Boisselier chemist and CEO of Clonaid, cloned Eve the first baby to be cloned and was 7lbs; she is known to be a healthy and happy baby. Eve was created by an America woman of 31 years old who donated her DNA for a cloning process. The woman didn’t give her name, but her embryo was implanted and then gestated to the baby, with that it would make an identical twin as an exact genetic duplicate of the mother. The reason why she decided to donate her DNA was because her husband was infertile of resorted cloning.
...the scientists creating dolly starved the donor sheep’s cells to make sure they were inactive. The scientists then committed somatic cell nuclear transfer and took the inactive donor cells and fused them with an egg without a nucleus from a different bread of sheep. Then, continuing to use the reproductive cloning procedure, the scientist implanted the egg into a third breed of sheep’s uterus. When Dolly came to full term and was born, the scientist immediately recognized that the lamb looked very similar to the breed of the sheep who donated the DNA, and nothing like the sheep who donated the egg or gave birth to the lamb. Later on, DNA tests confirmed that indeed, Dolly was an exact clone of the DNA donor. On April 13, 1998 Dolly gave birth to a healthy lamb, proving her health to be standard. She would eventually have two more pregnancies and have five more lambs.
Not so far in the future, a young boy of the age of six, dying a heart-wrenching death, will only be able survive with a bone marrow transplant. His parents will have searched near and far for a match, but none will come to their aid. The only possible way that they can produce a perfect match for their son's bone marrow is to clone their son. Unfortunately, at this time this topic is still being discussed and debated upon with the government. Their only child that has been their treasure for six years might die. A clone of their son becomes their apple of aspiration to keep the treasure from being buried.
Human cloning research has once been the subject of terrifying science-fiction films and novels, science experiments gone wrong, accomplished only by the evil scientists twirling their moustaches. However, ideas presented on page and screen are rarely accurate. The possibility of cloning an exact copy of another human with one already fully developed is almost impossible, but through meticulous research, scientists have discovered the numerous benefits of cloning humans, either with individual cells or an embryo.
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.
Many animals - including frogs, mice, sheep, and cows - had been cloned before Dolly. “Dolly the sheep was born in 1997: They take the nucleus of a cell from the original animal and inject it into an egg whose own nucleus has been removed”(Said Para 35) “From 277 cell fusions, 29 early embryos developed and were implanted into 13 surrogate mothers. But only one pregnancy went to full term, and the 6.6kg Finn Dorset lamb 6LLS (alias Dolly) was born after 148 days” (“Areas…”). Many other animals just like Dolly are cloned today and no one really cares because they are animals and do not matter. But the truth is that any living being is precious including plants as they breath just like humans do and hence they should not be cloned for experiments or any other kind of benefits.
Cloning is a biological process in which an identical copy of an organism is made. Scientists have been cloning since the 1800s, but only just successfully cloned the first mammal from an adult cell in 1996, Dolly the sheep. Dolly became very famous for this, although she only lived to be 6 years old, about half the lifespan of a normal sheep. Because of this, some think cloning is a very dangerous process, while others want to continue it and clone humans as well.
People argue that cloning should or should not be permitted. Some people assert that animal cloning can lead to medical through and help with the endangered species. The article by Jenny Barchfield writes that “Brazilian researchers are turning to cloning to help fight the perilous decline of several animal species” (Barchfield). The scientists are trying to use cloning to help endangered animals from extinction. Cloning could help create an animal from endangered species to prevent the animals from extinction. This is very important to keep animals from extinction, because once they are all gone it is very hard to get them back. Another scientist states that cloning could be very useful to cure human from diseases.By producing organs from animals and transplanting it into human to cure the disease (Gardels). The cloning of animals could be also very useful to the humans. Using this technology could create an organ from an animal to transplant them instead of the diseased human organ to help cure the
Cloning involves the process of producing a cell, tissue, or even a complete organism from a single cell. The DNA sequence is replicated from the original biological unit. There are two types of cloning, natural and somatic cell transfer. Cloning of plants or bacteria is natural. Plants have been duplicated for many years by replicating itself and growing. Bacteria are cloned through the process of mitosis, division of a single cell. Somatic cell transfer cloning is completed when cells are copied and transferred. Genes maintain genetic codes that hold our inherited information. Gene mapping is used to establish order.
Sally: Interestingly enough, I was just reading about this topic in a magazine. I was amazed at the simplicity of the cloning process used by Dr. Wilmut and his colleagues. The process of cloning a sheep begins by taking the cells from the udder of an adult sheep, and placing them in a culture with few nutrients. The purpose of this is to starve the cells so that they stop dividing. This switches off the active genes. While they starve these cells, they take an unfertilized egg from a different ewe, and remove the nucleus from this unfertilized egg. Then, they place the unfertilized egg cell next to one of the original starved cells
