Pros And Cons Of Therapeutic 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

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?

Cloning is a number of processes that are used to create genetically identical copies of an organism. Researchers have cloned a number of biological materials, such as genes, cells, tissues and whole organisms, including sheep 's and horses. Cloning can happen naturally in identical twins, but it can also be done in a lab. ("Cloning Fact Sheet").

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

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.

When Dolly, the first cloned sheep entered in the news, the cloning controversy is becoming more prominent. Not only researchers, the general public became interested in knowing how cloning is done as well as engage in the pros and cons.

Cloning is a process that involves removing the chromosomes from an animal’s egg cell and replacing them with chromosomes taken from a cell belonging to a different adult animal. The copied material, which has the same genetic makeup as the original, is referred to as a clone. There are three different types of artificial cloning: gene cloning, reproductive cloning and therapeutic cloning. Cloning is a very delicate process because many cloned animals resemble animals that are born prematurely. The problem seems to found in the genes because certain genes get turned on or off when a cell becomes specialized during development.

There are two main types of cloning that are known about, therapeutic cloning and reproductive cloning. Therapeutic cloning is when you take a small sample of DNA and insert into an embryo to make the embryo to have healthy parts. The parts are accepted by our body because they are from your DNA. Therapeutic cloning does not happen naturally in nature and it is asexual. Reproductive cloning is another type of cloning and unlike therapeutic cloning is sometimes occurs in nature. An example of natural reproductive cloning is meiosis and plants. This is asexual as well since it is an exact replica of DNA from one sample. Cloning may have many benefits but it has downsides. Cloning is a crude science that should not be researched upon because of its

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.

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).

Cloning is the process of creating a copy of something. In genetics cloning refers to the process of making an identical copy of the DNA of an organism. Human cloning is basically making a person exactly like the other, same exact features and characteristics etc. There are three different types of cloning and they are Recombinant DNA Technology or DNA cloning, Reproductive cloning, and Therapeutic cloning. Cloning can cause many problems to the animal that is being cloned making it impossible for them to live a normal life.

In the summer of 1996, an animal unlike any other was born unto the world. Roughly three feet high and covered in an insulating material, there were countless others that looked nearly identical freely roaming the countryside. But this animal was special; it was precisely identical to one of its brethren. Dolly the sheep was the first ever manmade clone, an exact copy of its genetic donor. In the fifteen years since the birth of Dolly cloning technology has been improving at a steady pace, and now humanity as a whole is at an impasse: human clones. Scientists are very close to being able to clone a human being, but should they? A ban on human cloning issued by the World Health Organization is in place (World Health Organization 1) but it

Many Americans do not understand how risky it will be to clone a human, not to mention how hard it is to clone an animal. Many news article and publications offer this information to the public, because many scientists will not address the media with the real facts. In an article titled, “Creator of cloned sheep, Dolly, says he wouldn’t want to make copies of humans”, Dr. Wilmut stresses that only 1-5% of those embryos used in cloning result in live animals, and survivors are plagued with obesity, kidney problems and other troubles, and even Dolly is suffering from arthritis (1). Most cloned animals, like cows, pigs, goats, sheep, die during embryonic development, and others are stillborn with monstrous abnormalities. Bloated mothers have laborious miscarriages, and occasionally die themselves. The clones usually struggle for air in intensive care units, only to have to be euthanized, the process of ending the life of an individual suffering from a terminal illness or an incurable condition, according to an MSNBC article titled, “Much confusion over cloning” (1). The risks and uncertainties associated with the current technological state of cloning are the basis for why
