For decades, cloning was merely a topic mentioned in the text of science fiction novels. It was simply a fictitious fantasy that proved to only be for entertainment purposes. However, while all those novels and films were being produced, a multitude of scientists attempted to make what society thought of as a dream, into a reality. The science of cloning is the process of making genetic duplicate of an organism. The scientific history of cloning spans more than 100 years dating back to 1885, and still going strong today. In general, there are two main purposes for cloning: therapeutic or reproductive. Reproductive cloning is performed with the intent of making a complete organism. Therapeutic cloning is performed to harvest stem cells for use in medical treatment, such as cloning organs for transplant. There are benefits and consequences for each process that have sparked ethical and scientific debate over the years. With the help of advancements in technology in the future, cloning can provide medical breakthroughs.
The process of cloning has existed for decades. Plants have been cloned for years now, although, cloning was never recognized until February 22, 1997 when the first mammal (Dolly the Sheep) was cloned from an adult cell (“Cloning Dolly The Sheep”). Dolly was named after Dolly Parton, the mammary cell that was cloned after giving birth at the Roslin Institute. The cloning of Dolly sparked much discussion and debate that has stuck around today. Dolly was the first successful reproductive clone. What first started out as the first ever demonstration of artificial embryo in 1885 quickly transformed into the success of cloning animals such as sheep, cows, and mice (“The History of Cloning”). With the help of decades of me...

Therapeutic cloning is the process whereby parts of a human body are grown independently from a body from STEM cells collected from embryos for the purpose of using these parts to replace dysfunctional ones in living humans. Therapeutic Cloning is an important contemporary issue as the technology required to conduct Therapeutic Cloning is coming, with cloning having been successfully conducted on Dolly the sheep. This process is controversial as in the process of collecting STEM cells from an embryo, the embryo will be killed. Many groups, institutions and religions see this as completely unacceptable, as they see the embryo as a human life. Whereas other groups believe that this is acceptable as they do not believe that the embryo is a human life, as well as the fact that this process will greatly benefit a large number of people. In this essay I will compare the view of Christianity who are against Therapeutic Cloning with Utilitarianism who are in favour of Therapeutic Cloning.

Cloning is a DNA sequence, such as a gene, that is transferred from one organism to another and replicated by genetic engineering techniques. This means to reproduce or propagate asexually and some sexually. Cloning is made when you have several embryos and you try to duplicate them to produce more eggs which is called SCNT. SCNT (Somatic Cell Nuclear Transfer) is used so that they can take a piece of DNA from an egg and transfer it to another egg after the nucleus has been eliminated by an ultra violet beam. This technique is really hard to accomplish but can be done by well experienced scientists. There are many reasons why scientist would like to clone, and two of the main reasons are finding a cure to certain types of diseases and helping the endangered species come back to life like they once were.
Cloning has been in nature for thousands of years, a clone is a living thing made from another consisting of the same DNA. For example identical twins are clones because they have the same DNA but the differ because the twins begin after conception when a zygote, a totipotent stem cell, divides into two, some plants self-pollinate and produce a seed, which in turn, makes plants with the same genetic code (Hyde). According to the Human Genome Project there are three types of cloning, DNA, therapeutic and reproductive; DNA cloning involves transferring DNA from a donor to another organism, therapeutic cloning, known as embryo cloning, involves harvesting stem cells from human embryos to grow new organs for transplant, and last is reproductive cloning which creates a copy of the host (Conger). One of the earliest cloned animals was a sea urchin by Hans Dreisch in the late 1800’s. Unlike Victor Frankenstein, Dreisch’s goal was to prove that genetic material is not lost in cell division, not to create another being, (History of Cloning) stated by Frankenstein “that I might infuse a spark of being into the lifeless thing that lay at my feet.” There are many ways an animal...

Just in a span of fourteen years the annual deaths related to Alzheimer’s has become twenty-five times greater. Both by external sources demonstrate that Alzheimer’s has been a problem for a while and will continue to increase if we do not find more efficient treatment methods in the near future.
First, what exactly is cloning? In biology, cloning is used in two contexts: cloning a gene, or cloning an organism. Cloning is the reproduction of a human or animal whose genetic substance is identical to an existing being, such as an embryo or fetus. This is reproductive. Cloning a gene means to extract a gene from one organism and insert it into a second organism. Cloning an organism means to create a new organism with the same genetic information as an existing one. This is therapeutic.
Cloning has become a major issue in our modern world, from moral, ethical, and religious concerns, to the problem of financial and government support. Human cloning is one of the most controversial topics, and because of this, many of the new important discoveries and beneficial technologies have been overlooked and ignored. Reproductive cloning technology may offer many new possibilities, including hope for endangered species, resources for human organ transplants, and answers to questions concerning cancer, inherited diseases, and aging. The research that led up to the ability to clone mammals started more than a century ago. From frogs to mice to sheep to humans, reproductive cloning promises many possibilities.
Alzheimer’s disease is rising at a very high rate. “The number of new cases per year is estimated at 360,000 equating to 980 new cases per day or 40 new cases every hour” (Cummings and Cole 1) This evidence shows that an increasing number of people will discover the effects of a cognitive impairment that will most likely be due to Alzheimer’s disease. As people age, their risk of being diagnosed with this disease increases ...
In recent years our world has undergone many changes and advancements, cloning is a primary example of this new modernism. On July 5th, 1995, Dolly, the first cloned animal, was created. She was cloned from a six-year-old sheep, making her cells genetically six years old at her creation. However, scientists were amazed to see Dolly live for another six years, until she died early 2005 from a common lung disease found in sheep. This discovery sparked a curiosity for cloning all over the world, however, mankind must answer a question, should cloning be allowed? To answer this question some issues need to be explored. Is cloning morally correct, is it a reliable way to produce life, and should human experimentation be allowed?

Cloning, especially human cloning attracts increasingly more attention after the first mammal cloning animal Dolly born in 1997. Cloning is divided into two categories: therapeutic cloning and reproductive cloning. Therapeutic cloning is more related to tissue level cloning to transplant healthy cells and reproductive cloning is individual level cloning. Thus, the term cloning in this essay is used to describe both individual level and tissue level cloning. Public have different views. Some people support it because of its medical value, yet some people argue that it may bring many safety risks and moral problems. Hence, decisions ought to be made to identify the extent of cloning. Therefore, this essay introduces two major benefits of human cloning on disease therapy and analysis two arguments against it on safety and ethical issues.
been made possible but yet a majority of them have died in early stages of development or after birth according to the study of the cloned sheep, Dolly (Magalhães 1). Those who make it suffer from several defects acquired from birth (Magalhães 1). During recent experimentation it took scientist Ian Wilmut of the Roslin Institute in Edinburgh, Scotland, and his colleagues who created Dolly (a cloned sheep) 277 tries before they got a healthy, feasible lamb (Human Cloning 1). Due to the complication of human cloning even more deaths and deadly birth defects can be expected (Human Cloning 1). Even though human cloning has never been performed, one likely possibility is that babies born through this process will as well feature lethal birth defects (Magalhães 1).

Sally: Interestingly enough, I was just reading about this topic in a magazine. I was amazed at the simplicity of the cloning process used by Dr. Wilmut and his colleagues. The process of cloning a sheep begins by taking the cells from the udder of an adult sheep, and placing them in a culture with few nutrients. The purpose of this is to starve the cells so that they stop dividing. This switches off the active genes. While they starve these cells, they take an unfertilized egg from a different ewe, and remove the nucleus from this unfertilized egg. Then, they place the unfertilized egg cell next to one of the original starved cells
