The idea of the possibility of cloning has long interested scientists from all over the world. The ability to create another life without the need to reproduce, simply a petri dish and some cells, is something that has been attempted to be done for decades. There are endless possibilities of the uses that cloning could bring, and it excites many and equally terrifies others. In was in 1997 when there was a big breakthrough of cloning occurred: the “birth” of Dolly the ewe. Dolly was cloned from an adult sheep in Scotland. Dolly was the beginning of the experimentation of cloning full mammals. We now clone many mice and claves all cloned from adult cells that still now fascinate many scientists. However, the idea of cloning and cloning …show more content…
From tadpoles and amphibians, then came fish and insects and finally in the 1980s experimentation began on mammals. Before the cloning breakthrough of Dolly the ewe, many scientists did not believe it was possible to clone using DNA from adult animals. The scientists thought that cell differentiation was unalterable. However, the scientist Dr. Wilmut and his partners resolved this problem using a starvation technique. They starved adult cells of their nutrients and then the cells became inactive. Then once the cells were inactivated, the scientists introduced the DNA from a different cell and reconfigured the DNA to show all of its genes. The result of the cell was capable of making an animal practically genetically identical to the DNA of the original donor.
Uncovering the replication stage and finding out how to manipulate and control the cells in mammals was a much more difficult task than what many thought, which is why the successful experimentation on mammals was not until much later on, 30 years after the first successful copy of a tadpole. Currently there is still much debate and wonder on the idea of cloning. There have been no real advances in human cloning due to the ethical and moral issues that many people have on the idea of actually cloning a full human. As well as it has been known that cloning is
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
Animal cloning started without the world even knowing. First, an animal clone is “an exact physical copy of one ‘parent’” (Newman 12). “Animal cloning experiments began in the 1960’s. Frogs were the first subjects. By 1987 scientists had begun cloning cows and other mammals” (Newman 12). Dolly the sheep was the first big cloning success, credited to Ian Wilmut in 1996 (Praded 21). This sheep was a scientific breakthrough, but it also caused many people to question the intents of scientists. Many people wondered if scientists would clone humans next. The original intent of animal cloning was not for the food industry. The reason animal cloning started was to find a way to help cure currently untreatable diseases (“Why Do Scientists Clone?”). By cloning cells, scientists will be able to manipulate the cells to become something new.
Six years ago, an event in genetic history changed our perspective on "reproduction" and added to our conscience a new element in the study of biology. On February 23, 1997, the world was introduced to Dolly, a 6-month-old lamb that was cloned from a single cell taken from the tissue of an adult donor. Ever since the birth of this sheep, a question that never before existed now lingers in the mind of many: should human cloning be a part of our society?
The topic of cloning has been a science fiction legend until Dolly, the first cloned mammal, was born in the late 1990s. Dolly’s cloning renewed the interest in the potential of human cloning as seen in science fiction. Cloning has been done since the 1950s, but every cloning experiment included problems. When cloning mice, researches can use thousands of eggs to fix errors, but human cloning cannot use the same knowledge learned from cloning cows. With human cloning there is an “…extremely high rate of death…” and chance of abnormalities that cause the ethical concern for cloning humans (Rettner).
Numerous attempts are being made in the hopes of finding an answer to the problem of the millennium. The concept of cloning has caught scientists attention throughout this past century. "The world has to come to grips that the cloning technology is almost here,” a representative for a European research group, Panos Zavos. Clones are life forms that have identical genetic coding. A clone is an organisms replica. Originating in the late 1880’s; the first record of synthetic embryo
We’ve all seen the movies. A person gets in a tube. The scientist, usually equipped with crazy hair, pushes a few button and a huge flash of light occurs. Two people walk out completely identical. And of course we know movies would never lie to us. The first cloning of a mammal, while not quite the mad scientist scene expected, was still an amazing event. It was a sheep, later named Dolly. One day, in the not so distant future, we can all use these techniques to clone our dearly passed pets or even family members. Dolly was cloned in 1996 using reproductive cloning and since then many things thought unthinkable twenty years ago have been achieved.
Cloning is the production of an organism with genetic material identical to that of another organism. The word cloning comes from the Greek work klon, meanings “twig,” involves the production of genetically identical animals by a process of nuclear transfer. On July 5th, 1996, at the Roslin Institute in Edinburgh, Scotland, a scientific breakthrough occurred when Dolly, a Finn Dorset sheep, was born. (Seidel, 682) “We transfered 29 eggs into a recipient and only one of them became a live lamb. So you can see it’s a very exciting and encouraging result. The efficiencies are poor and there’s a need for a lot more research.”(npr.org) Where it is a controversial subject, the cloning of dolly the sheep affected the world in a positive way and helped advance medical research in finding cures for diseases.
God and Nature first made us what we are, and then out of our own created genius we make ourselves what we want to be… Let the sky and God be our limit and Eternity our measurement – Marcus Garvey (1887-1940).
The science in biology allows us to discuss living things, organisms, and the creation of life. The United States banned all kinds of cloning in 2005, but there is still a curiosity in if it can lead to improvement in human existence. Cloning is about composing an identical organism out of the given DNA and constructing it to appear as natural as it originally did. Experiments and approval for human cloning may be in many years to come and out of reach today. As far as animal cloning, we know to a point it’s safe. If we continued the exploration in genetic replication on species, breeding animals can enable us to provide food for a growing global population, and save endangered species. An article like Dolly the Sheep’s Fellow Clones, Enjoying Their Golden Years, the writer brings attention to cloning as being a possible answer to the problems we harbor
Cloning has opened the doors and provided optional ways to resolve various world problems. Right now, cloning is being used for many purposes in improving the lives of the people, especially therapeutic and reproductive cloning. Therapeutic cloning is leading to find new treatments or cures for common diseases that are affecting people around the world, while the goal of reproductive cloning allows people to produce things that died to help seek redress for their losses, and the idea of cloning more things can be used to serve difficult tasks in the world. Not only that, cloned animals are used for their organs to replace damaged parts of a human body. The science of cloning can lead to many unknown consequences; however, we should not consider
Cloning, an ethical issue that has been pressed across the globe, has become a substantial debate throughout a majority of nations. The incorporation of a new type of reproduction in the United States has a plentiful amount of benefits for certain animals and objects, but duplicates of humans is hard to comprehend for many people across America. Currently, cloning is an interesting topic that could become a new way to improve reproduction of animals and humans, prevent diseases, and increase the overall health of Americans.
From Star Wars to the Jurassic Park movies cloning has always been a science fiction story that was light years ahead of us. But with recent evidence and research to clone living organisms, the far away fantasies of cloning we have been dreaming about for many years is rapidly becoming a reality, even faster than we think. Twenty years ago, in 1997, Dolly the Sheep was the first successful clone to be produced from an adult mammal. In the article “The Coming of Clones” American Scientists announced in 2013 that they had for the first time successfully obtained stem cells from cloned human embryos (the building blocks of cloning life). Due to this announcement and the cloning of Dolly, cloning has become a debatable topic that has both negative
Introduction- Cloning is defined as two organisms having identical genetic DNA and has been around since the early 1800s. When people think of the word ‘cloning’ many think of Dolly the sheep; however, the first organism to ever be cloned was a sea urchin in 1885. When scientists created Dolly, they took a cell from the mammary gland from an adult Finn Dorset sheep and an egg cell from a Scottish blackhead sheep. Dolly’s white face was the first sign that she was genetically modified because if she wasn 't, she would have a black face like her surrogate mother. After her procedure, the scientists named her after the country singer, Dolly Parton. (1,2,3,5)
Imagine a future where humans are manufactured, a future where humans are created by science, a future where humans are the new lab specimen. Human cloning is like opening Pandora's Box, unleashing a torrent of potential evils but at the same time bringing a small seed of hope. No matter how many potential medical and scientific benefits could be made possible by human cloning, it is unethical to clone humans.
Scientific experimentation has led us to many great discoveries such as: Chemotherapy, heart surgery, and bone marrow transplants. Recently scientists have discovered a new way to heal humans. This is known as cloning. Although they have yet to clone a human they have cloned sheep. Cloning has brought up a huge controversy among the American people. There are two sides to the story. Either you agree with cloning or you don’t. The only way to help make that decision is to look at the good and bad points of cloning.
