What if you could bring back someone you love or a beloved pet from the dead? You may be able to do that in the near future with cloning. Cloning is when an organism is genetically identical to the individual from which it was asexually derived (Random House). Cloning was brought to light in 1997 when scientists successfully cloned a sheep. The birth of Dolly was a major scientific breakthrough. In writing this paper, I hope to shed light on what cloning is, the reasons to conduct cloning research, pros and cons of cloning, and what the future of cloning looks like. What is a clone? In simpler terms, it is an exact copy of the DNA of an original organism (Engdahl 17). Cloning is something that’s been around for a while. Plants, like strawberries and potatoes, use this technique to grow. “When plants like strawberry plants and potatoes send out runners, modified versions of a stem, new plants grow wherever the runners take root” (Engdahl 17). Animals can also clone themselves too. A not so obvious …show more content…
For example, scientists want to genetically engineer agriculturally important animals so they can pollute less, grow more rapidly, and produce higher quality meat or milk (Levine 165). They also hope to turn animals into biological factories, capable of producing medicines and other products at a lower cost than traditional manufacturing (Levine 168). Cloning can also be used to help strengthen the food supply around the world. Researchers have been able to clone disease-resistant crops and livestock. Plant cloning has created many benefits for the agricultural industry. For example, cloned plants are more predictable and the yields are more reliable. They are also able to create pesticide resistant plants which save the agricultural industry millions of dollars (Levine 166). As for human cloning, scientists want to use cloning technology to be able to understand diseases
Cloning, upon first hearing the word cloning, the thought of Dolly the sheep pops into the mind. The first and most used type of cloning though is not the type that creates animals, but rather DNA cloning. “Cloning is an umbrella term that science uses to indicate the duplication of biological material.”(Human Genome Project) Cloning is further broken down into three categories. The first is DNA cloning, which is the replication of DNA strands. DNA cloning is usually the process of getting a cell to replicate a desired gene for us. DNA cloning has been used since the 1970’s and has persisted as an effective cheap means of replicating DNA of interest in a foreign host cell. “To "clone a gene," a DNA fragment containing the gene of interest is isolated from chromosomal DNA using restriction enzymes and then united with a plasmid that has been cut with the same restriction enzymes.”(Human Genome Project) Plasmids are not part of the chromosome but they replicate along with the cell when it replicates and divides. Since they are not a part of the chromosome they are easier to isolate and manipulate without affecting the cells function. “When the f...
The objective of this essay is to inform the reader(s) about human cloning. I believe that human cloning is morally wrong because one should not have the right to avoid daily responsibilities by getting someone else to handle them. There will be four sections of this paper that will be discussed. Firstly, there is an argumentative section, which will have premises along with a conclusion for an argument made against human cloning. Secondly, an explanation section, which explains how the argument against human cloning obeys the rules for a good argument. Thirdly, an objection section to where there are arguments that violates mine in order to demonstrate how objectors might object to the argument. Lastly, there will be a conclusion where I discuss
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...
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.
The goals and purposes for cloning range from making copies of those who have died, to better the engineering of offspring in humans and animals (Hawley, 1998). Cloning could also directly offer a means of curing diseases or could offer a technique that could extend means to acquiring new data for the sciences of embryology and how. organisms develop as a whole over time. Currently, the agricultural industry demands nuclear transfer to produce better. livestock, and cloning could massively improve the agricultural industry as the technique.
Cloning is a recent innovative technique the National Institute of Health defines as a process employed to produce genetically identical copies of a biological entity. Depending on the purpose for the clone, human health or even human life can be improved or designed respectively. “Somatic cell nuclear transfer (SCNT) is the most common cloning technique. SCNT involves putting the nucleus of a body cell into an egg from which the nucleus has been removed."^1 From this technique, an embryonic cell is activated to produce an animal that is genetically identical to the donor. Today, human cloning still remains as a vision, but because of the success of Dolly, the lamb, researchers are becoming more confident in the ability to produce a genuine
It is essential that human cloning is outlawed. It is salacious to perform, research, and promote these experiments on human subjects; it is neglectful, and shrewd to make the presence of this objective technology legal, let alone obtainable. Not only is human cloning hazardous and illogical, but morally incorrect and greatly dishonorable. The most alarming thought referring to human cloning is that it has the power to alter the foundation, that we as a nation, are assembled upon. What occurs after we take things too far and lose control? What happens when we are no more satisfied in simply seeking education of the physical universe? We will cross the line between natural and synthetic. What will differentiate God from man? Do we have the authorization to change the evolution of life? Science has proven that we can reproduce humans both naturally and unnaturally, but that does not mean that mean we should stop questioning whether or not we should scientifically reproduce humans.
Many people say that everyone in the world has a twin. Today, science and technology has the ability to make this myth reality through the process of cloning. I am strongly against cloning for many reasons. People should not utilize cloning because it would destroy individuality and uniqueness, cause overpopulation, animal cruelty, it is against morals and ethics, and it violates many religious beliefs.
Cloning can increase livestock throughout the world to provide for the growing population and consumption of food in the world.
Cloning is a process by which genetically equal organisms are created with the same DNA. In simplest terms, clones are like twins born at different times. This procedure poses various dangers to society and humankind. One of the greatest threats this procedure creates is among
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?
Recent discoveries involving cloning have sparked ideas of cloning an entire human body (ProQuest Staff). Cloning is “the production of an organism with genetic material identical to that of another organism” (Seidel). Therapeutic cloning is used to repair the body when something isn’t working right, and it involves the production of new cells from a somatic cell (Aldridge). Reproductive cloning involves letting a created embryo develop without interference (Aldridge). Stem cells, if isolated, will continue to divide infinitely (Belval 6). Thoughts of cloning date back to the beginning of the twentieth century (ProQuest Staff). In 1938, a man decided that something more complex than a salamander should be cloned (ProQuest Staff). A sheep named Dolly was cloned from an udder cell in 1997, and this proved that human cloning may be possible (Aldridge). In 1998, two separate organizations decl...
The Benefits of Human Cloning In recent years, many new breakthroughs in the areas of science and technology have been discovered. A lot of these discoveries have been beneficial to the scientific community and to the people of the world. One of the newest breakthroughs is the ability to clone. Ever since Ian Wilmut and his co-workers completed the successful cloning of an adult sheep named Dolly, there has been an ongoing debate on whether it is right or wrong to continue the research of cloning (Burley).
Genetic engineering is a way in which specific genes for an animal or plant can be extracted, and reproduced to form a new animal or plant. These new organisms will express the required trait for that gene. This practice is a very controversial topic within the scientific world. It is being implemented in various areas such as agriculture even though there are many alternatives that can be found for genetic engineered crops, such as organic materials and reducing leeching of the soil. The controversy regarding this practice occurs as it is believed to contribute both negative and positive implications and dangers, not only to oneself but the environment as a whole. Genetic engineering increases the agricultural economy, the yields of agricultural produce, and also causes negative effects on the ecosystem.
Cloning is propogate, an organism or cell, as a clone by a form of asexual reproduction. There are two main types of cloning known as therapeutic and reproductive cloning. Therapeutic cloning is when a scientist creates cells that can be transplanted into the patient
