The Pros And Cons Of Cloning

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.

The first Mammal to be cloned was Dolly the sheep. That’s when cloning really started to take off. Dolly lived from 5 July 1996 to 14 February 2003. Since the cloning of Dolly just over 20 years ago, 22 other species of animals have been cloned since. ("Cloning Dolly The Sheep") (“How many

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.

Dolly the sheep was the first mammal to be cloned, her birth being announced on February 22, 1997. She was created by a group of scientists from Scotland where she lived for six and a half years before being euthanized due to progressive lung disease and severe arthritis. Dolly was

the attempts made at adult mammal cloning actually work. Dolly’s status as the first true clone of

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

Structure, function, and growth discoveries in biology happen every day. Humans have always questioned if we have the technology and capability to manipulate life. Questions such as: Can scientists replicate DNA and get rid of diseases in DNA? Can we create an almost perfect species? Could we live in the world, where animals are never endangered, and ecosystems would be plentiful of life? A place where cloning animals are improving our way of living and advancing our technology. Yet, in many places around the world cloning on animals, especially humans, there is ban from any sort of experimentation. In the article Dolly the Sheep’s Fellow Clones, Enjoying Their Golden Years, we peek into the misconceptions people have about cloning experimentation.

The sheep named Dolly was successfully cloned from an adult somatic cell using the above laboratory technique. She was cloned by Ian Wilmut, Keith Campbell and colleagues at the Roslin Institute, part of the University of Edinburgh, Scotland (Edwards, 1999). The experiment started with 277 fused eggs but only 29 fused eggs became fertilized. The fertilized eggs were transferred into 13 sheep, however only one sheep became pregnant successfully. The other remaining 12 sheep failed to pregnant and several dead fetuses were then discovered from them. The successful clone, Dolly was born on July 5, 1996. Unfortunately, Dolly only live up to the age of six which is

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)

Debates about cloning only initiated after the first cloned mammal from an adult somatic cell in 1996 was officially declared a success. The cloned mammal was a sheep named Dolly, which then appeared to suffer from health conditions that ended her life at a young age (Pano, 36). “This ignited a worldwide controversy about whether or not cloned animals die prematurely” (Lew, chapter 1).

In 1967, Derek Bromhall decided to tackle the untouched region of mammalian cloning. In order to attempt nuclear transfer for mammalian embryos, Bromhall developed the microsurgical equipment and techniques that were required. By using a glass pipette, Bromhall transferred the nucleus from a rabbit embryo cell into a rabbit egg without a nucleus. He concluded his experiment as a success when an advanced embryo was produced. Although, cloning had led to marvelous discoveries through various experiments, it was not until 1996, when the first mammal was created through somatic cell nuclear transfer. In this astonishing experiment, Ian Wilmut and Keith Campbell created a lamb by transferring the nucleus from a lamb sheep udder cell into an enucleated egg. Since

The cloning experiments of the Dolly sheep involved 277 cell fusion attempts; the responsible ones managed to generate 8 embryos successfully and of them one only survived; "Dolly" With these figures, one can estimate the number of human lives that can be lost in the performance of this experiment. For this reason, the same Dr. Alan Colman, who participated in the cloning of the sheep Dolly opposed in August 2001 to the idea that some scientists had to start cloning humans.
