Imagine a world where a woman could bring back her deceased husband, by giving birth to him. Or, a man could bring back his mother and raise her as his daughter. If we have a living cell of a dead person, certainly, we could in theory clone that individual. We published a paper about a year or two ago, where we show we can actually now create human embryos that are genetically identical to a normal embryo. The only way you would really know whether you could clone a human being is actually implant that embryo into the uterus of a surrogate mother. Of course, we cannot implant those, that would be considered unethical so it’s unclear whether or not they would give rise to a human being.
Society has vehemently rejected reproductive human cloning. In this climate, it is extremely difficult for geneticists to obtain funding for their research. There is also a shortage of material. So, one of the problems with human cloning is the supply of eggs. So with a mouse or cow, we can get literally hundreds, if not, thousands of eggs. We can go to the slaughter house, for instance, get them for a dollar each, and get thousands of these cow eggs. With the humans, it took us over a year to just get 5 eggs. Even if you have the eggs, it could take hundreds of pregnancies to perfect human cloning. A process that could result in scores of babies with horrific genetic damage. There’d be very much like if you want to clone your child, you would sending them up with a rocket, with a 50-50 chance that it would blow up. In most of the world, cloning humans is not illegal. One day, a rogue scientist will pull it off. But, cloning a person is not the same as duplicating a person. A lot of people, you know, who have the pets, they want often to clone them. They want Fluffy back, and what I tell them is that “You are not gonna get Fluffy back.” As a matter of fact, we actually clone entire herds of cows, from a single cell from the same animal. And they develop a whole hierarchy just like we do in humans. So you have timid cows, and aggressive cows, and they are all clones. So they develop their own behavioral pattern, so the environment has a very profound impact on your development. Let’s say we decide to take DNA from Einstein’s hair and grow some new Einsteins. Those clones would not be the man who wrote E=mc2. Each would have a unique personality shaped by his environment. Clones are like identical twins, born years apart. They may be similar, but they will not be the same. Perhaps the key to life after death is not to grow an entire new body, but to resurrect the one you have.

Ever since the birth of the first cloned sheep, named Dolly, the dream of human cloning has existed (Van Dijck, 1999). Cloning a mammal is described as the manipulation of an animal or human cell in order to create an identical copy of that animal’s or human’s nucleic DNA (Andrews, 1997). Though the dream of a human clone also comes with a lot of controversy regarding ethics and morals. Embryotic stem cell research, which could lead to a renewable source of human tissue, cells and eventually entire organs (Bowring, 2004), is highly controversial due to the necessity of placing a cloned embryo into a woman’s body in order to achieve that research. Politicians differentiate between therapeutic cloning and reproductive cloning as they refer to the second as “implanting a cloned embryo in a woman's womb” (Bowring, 2004), as for the embryo itself the research is not very therapeutic. Furthermore cloning by transfer of nuclei is not very effective yet as only 1% of manipulated sheep eggs reach adulthood and the number is even lower for other animals (Solter, 2000). The question whether human cloning will ever be possible and ethical remains to be answered but it seems certain that extra research in embryotic stem cells will improve techniques and success rates, which eventually brings the realization of a human clone closer one step at a time.…

As revealed earlier, cloning humans has a high failure rate, because there are many barriers put in by nature to prevent an “unnatural” event from occurring. These barriers can happen anytime during the cloning process. For example, the enucleated egg might not be compatible with the donor nucleus, the newly transferred nucleus may not grow and develop properly, the step where the embryo is implanted into the surrogate could fail, or the pregnancy may fail. Even if the pregnancy succeeds, there is no guarantee that the clone will act like a clone unless the right genes are activated. In a transferred human cloning, the scientist has to re-program the nucleus and force it to pretend as if it belongs in an early embryonic stage. If the nucleus is not programmed properly or completely, the embryo will more than likely become abnormal or die. Now, if the embryo manages to pass all of the post-zygotic barriers, “there is a possibility that the [fully developed] cloned individual might carry certain abnormalities…” causing them to live a shorter life span than expected (Wickman). There are also other concerns, besides health-related, such moral issues. The ability to clone individuals could lead to an out-of-control situation created by someone who wants to create an army of genetic replicas by abusing the new…

· Cloning would also deal with killing embryos. You might not have known, but Dolly, the sheep that was cloned in 1996, was one of over 200 sheep embryos and hers was the only embryo that survived. The rest died or were thrown away. Imagine if the failure rate was that high when we started to clone humans. More than 200 embryos, the start of 200 human beings, would die for the sake of just one embryo that would have the same DNA as some one else (LiveScience.com 2009).…

Over the years, science and technology have expanded to make it possible to create identical creatures. While new cloning technology is a great advancement, it raises a plethora of moral and ethical questions. Cloning may bring about new ways to find cures for babies, according to Philip M.

Animal cloning, wow, 30 years ago this could only be thought of in Star Trek but now it’s a reality; and with this reality comes a whole myriad of ethical issues, but to fully understand animal cloning we have to know what it is so, what is animal cloning? Do we just zap a sheep and out pops another? No, it’s actually quite an intricate process but basically it involves this, you take the cell from a male sheep, combine it, using electric currents, with the egg of another sheep and then insert the blastocyst created into a surrogate sheep creating an exact replica of the donor male. But should we? I mean who are we to play god?…

Proponents of human cloning hold out two hopes for its use: (1) the creation of children for infertile couples (so-called "reproductive cloning"), and (2) the development of medical miracles to cure diseases by harvesting embryonic stem cells from the cloned embryos of patients (euphemistically termed "therapeutic cloning").…

Making a replica of an organism, sperm, egg, or anything else sounds pretty crazy. There will be those that will think cloning can be a great idea. The thing is that taxpayers will have to pay a certain amount of money to the government to fund therapeutic and reproductive cloning. However, any type of cloning should not be accepted. Many people believe that cloning can be beneficial, but it won’t be beneficial because humankind can actually handle life without making a replica. Some people would actually come to the point where they will take part of their bodies for granted, or another reason is that there will be those who won’t get the chance to experience life the natural way.…

Animal cloning is getting popular by scientists day by day after the success of the sheep Dolly which was the first animal clone in the world. Dolly was created effectively by Roslin Instute scientist in Edinburgh (TechNyou) and she was euthanized when she was six year old due to a virus-induced lung tumour (Mott M., 2004). Even though the relevant scientists report that there is no evidence that cloning might be the cause of the disease of Dolly (Mott M., 2004), most of the scientists agree that cloning animals cannot be excellent with the current technology. They further state that the technology must be more advanced for having perfect clones. However, this warning does not stop people who want to clone their pets to not to lose them. There are lots of companies like Genetic Saving and Clone, Lazarus and PerPETuate (Masterson U. O., 2012) which stock the DNA of the pets to clone them if pet owners offer a huge amount of money. It seems like that cats can have more than 9 lives now but cloning is not that simple issue it has its pros and cons. These pros and cons must be considered carefully before deciding the pets should be cloned or not.…

What is life? What defines a person? Do you believe humans should have the right to create life? Are there any consequences? In 1831 Mary Shelly wrote Frankenstein or; The Modern Prometheus, a magnificent depiction of a man taking up God’s role of creator of life. Victor wanted to achieve biological immortality. Yet, within the instance of success Victor outright rejected his creation as “monstrous”, a unit for being unworthy of human life. In this paper, I argue that Frankenstein and the idea cloning have a lot in common, because the two topics share pros and cons on behalf of their out coming result.…

For many years, scientists have been experimenting in the field of cloning. Cloning uses an egg cell and a somatic cell to make a duplicate copy of the organism. It is currently a highly controversial topic in the scientific world. Many people can benefit from cloning. From farmers to patients, not only does cloning help scientists discover more about genetics, it will also help a lot of people. However, there are also ethical issues with cloning, such as the use of embryonic stem cells and cross-species hybrids. For instance, at the Salk institute, a human-pig embryo was recently made and destroyed. The purpose of the experiment was to see if human organs could be grown inside a pig. The authors believe that we are still far off from accomplishing cloning of human organs in animals. I believe that cloning will help this world, but there needs to be restrictions on human cloning and cross-breeding.…
