Human Cloning Essay

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?

Can I get a show of hands of every one that has heard of the famous sheep that went by the name Dolly?

Dolly the sheep, a clone born in Scotland in 1996, was the first mammal to ever be cloned from an adult cell using nuclear transfer. Her birth demonstrated for the first time that even DNA from already specialised adult cells could be used to create an entire healthy organism.

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.

Cloning and genetically modifying humans is now more attainable than ever due to strides made by science. With a relatively short history, cloning and genetic engineering have been a new concept for many people in society with the first proof of cloning being dolly the sheep, the first successful clone born by the somatic cell nuclear-transfer procedure [1]. Cloning over the years has evolved and now could be used to someday help people requiring organ transplants, recover from traumatic injuries and aid infertile couples with its reproductive possibilities [4].

The ethical concerns with cloning didn’t become a problem until Dolly, the sheep, was created. Many years before Dolly very similar experiments were being performed; however, those experiments did not spark much public concern regarding cloning. Over fifty years

On February 24, 1997 history was made. The first cloned adult mammal was born through somatic cell nuclear transfer (McCuen, 11). Somatic cell nuclear transfer is when a nucleus of a mammary gland is removed and fused with an egg by using electrical pulses. The pulses prompt the egg to divide to form an embryo. The embryo is then transferred to a uterus where it is implanted to grow (McCuen, 10). Before the creation of Dolly, many scientists were unsuccessful in their attempts to produce a genetically identical copy of a cell. In the rare occasion that they were successful in their attempts, they would soon be discouraged due to the inability of the clone to sustain life. It took hundreds of attempts before Dolly’s team of scientist could obtain a successfully cloned sheep. Of the 277 successful transfers, only 29 became embryos. And of these 29 embryos, Dolly was the sole survivor (Sweat, 1). What sets Dolly apart from previous clones is the fact that she was cloned differently. Dolly was cloned not from sex cells but from mature mammal cells with no reproductive function (Sweat, 1). Even though Dolly was a

In July 2000, Dr. Ian Wilmut, a geneticist of Scotland publicized the cloning of a lamb named Dolly. Out of 277 attempts at fussing cells, only 29 of the fused cells became embryos, on which resulted in one pregnancy, which then

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

Cloning Dolly, the sheep in 1996 was a momentous moment in scientific history. Scientists removed the nucleus from one of Dolly 's skin cells and engineered an egg to be insert with then nucleus. This egg could have fertilized in a mothers ' uterus. Following this discovery, mice, pigs and cattle have been cloned based on the same concept. In 2012, a group of scientists took cloning a step further and cloned human embryos. With great certainty, human cloning will be banned by the government due to human rights. The government has already deemed it illegal to fund human cloning projects. Despite the human rights issue, cloning serves a great role in research. These cloned embryos will help understand the biological nature of human cells and the human body. Also the embryos will help advance medical treatments for a wide variety of diseases. Cloning is vital to genetic engineering. Problems do arise from such an advancement. Exploration of women would be a major issue due to the fact that these cloned embryos need to be implanted into a women 's ' uterus in order to under go gestation. Almost all scientific developments pose positive and negative outcomes.

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.
